i only know how this person looks and where this person works .

i met this person at there job and i didn't get a chance to get their name .

I was at the mall and a employee told me I was really pretty and kind of flirted with me . I was nervous and I rudely said "ok" . I'm 100% sure this person would've asked for my number if I would've have been so rude. I really wanna get to know this person better. How can I do that? Would it be ok if I called their job and explained what happened?

me and my boyfriend go to different high schools and he's really busy with basketball and i'm really busy with schools and although we're in the same city , i thought of it as a long distance relation. we barely get to see each other because one of us is usually promise and something. and now im punished b/c im teacher accused me of cheating on my midterms. and this time my mother took my phone. i have a laptop, no ipod or ipad or anything like that..how can i talk to my boyfriend? ( btw he lives like 10 minutes away from me, and im Only 15 & i dont have a car or a older sibling .

i know nothing about laptops and i dont want to try and solve the problem myself.. where/who/how can i get in fixed? how much does it cost?

i mistaken stepped on my laptop, although it didn't have any cracks in the screen when i turned it on the screen was darker and the colors were/are funny . i can still use it (im actually using it now) but i really need my screen back to normal so i can see clearly. its not black nor white or flickering , it looks as if tho someone turned down the brightest which isn't not true, i've checked several times. i've tried holding the power button for 30 seconds and even taking the battery out of it. im positive the cause is because i stepped on it, but how to fix it??? thanks in ADVANCE.

me and my boyfriend met in middle school and we both were suppose to go to the same high school .. but long story short -- he got in and i didnt . now i have a chance to go to the same school as him and i asked him "do you want me to go to school with you?" not that it was his discision but he responded " i dont know .thats up to you and your mother " . he was suppose to say **** YEAH, WHY WOULDNT I WANT MY GIRLFRIEND GOING TO SCHOOL WITH ME?! -___- that makes me think that maybe he doesnt want me ask school with him :/ maybe he's dating someone else or something like that . he once said "if we went to school together , we wouldnt have any problems" which is true b/c i wouldnt have to worry about him cheating or anything like that.. do you think he wants me to go to school with him?

i was a jecpenny model ages 3-11 and when i started middle school i put on a few pounds .. now im a freshman in high school and i weight 136 and im 5'4 . i work out 3 times a week and i eat like an average teen age girl ( probably not the healthiest ) but anyhow my mom hooked me up with this agent and long story start i need to lose 26 pounds at the least in 4 months . considing that i have a fair enough time , i really want to lose 10 pounds a month .. please give me some exercise plans or diet plans and no comments like "thats too skinny" "thats an healthy weight" blah blah blah, thanks in advance .

i try really hard to make good grades because i want to get stuff, go places, and i dont want to seem stupid.. im really good in math and i understand everything i do in science but it seems like the cause of my bad grades are because of quizes and tests . i study long and hard and i still dont have the grades i feel that i deserve . i have had my phone tooken and my mom wont let me go anywhere , honestly i never wanted to go to this school in the first place because i knew it was hard , my mom made me go because she wants to show off in front of her friends . WHAT SHOULD I DO ? i need my phone back now and i have a life and important places to go .. a C or anything above is good enough . how to convience my phone to give me my phone back ? allow me to go places ? and let me go to a different school second semester ? ( its too late to transfer this semester ) .

i was going thru my boyfriend of only 3 weeks phone & i read some of his messages . and i found a message that said " omg , i forgot you had a girlfriend .. now i feel bad about what we did " . what could WHAT WE DID mean??? should i be worried ? should i break up with him ? how should i approach him with this ?

Im a freshmen in high school & over the course of middle school i was really popular and everyone knew me. Now im at a new school with new people (some) people. I dress nice everyday and i have long hair and im far from ugly and theres really no reason to not like me. but senior girls always have something "smart" to say. Like today a senior guy walked up to me and started talking to me (named Kj) and i girl said " kj, you still talk to hoes?" and they always mugg me in the hallway and give me bad looks. And although my bestfriend goes to school with me i dont take any classes with her or any of my other friends. How to get people to not dislike me? And people who take classes with me to talk to me?

I have an samsung captivate in great condition and i really really want to get it off my hands . where can i sell it other than ebay or amazon or usell ???
