I live in Florida, so is the money going to expire by 2011 or does it need its original 180 days to expire? If its the 180 days rule then im in the clear! REPLY ASAP PLEASE!!!

I stated that in my essay, and my teacher told me that he wants an official statement that says that people that are 21 are more mature! I mean, thats what common sense is! but I'll appreciate it if you guys could provide that!

So I get out of USMCRD Parris Island, and I finish my MOS school! what gear will I be issued in my unit (which is going to be 4TH ANGLICO)?

How certain will I be if i join the SEALS that I will have my education within four years WITHIN the service, and my other question is how many college credits would I earn by the time that I finish my BUDS training and SEALS training..Im asking this question because I am about to take my oath in MEPS and I need to notify my Marines recruiter if I wanna be in the SEALS so I can take my physical training and switch my Marines contract from Reserves Marines, to active Marines.

Thank you in advance.

 I lived in Cyprus *** well, so as you may notice throughout my life and my early child hood I have been living in domesticated places which gave me the hard way of learning quickly ones of the most interesting cultures around right now.

I consider myself extremely lucky to have the knowledge that I have about the different cultures that I was in.

So here is the story, me and my girlfriend met in the most random way however we started dating even though her parents were against it for 5 MONTHS,.,5 months of begging and sneaking and all that,,,It basically was so hard but we made it through because we really love each other..however after these 5 months we made it...she told her mom that we were dating (she was shocked) but her mom loved me..she told her dad (he was the one saying a HELL NO from the beginning) however he was really nice to me..he didn't show that he hated me when i was around him or when i was taking her on dates.

a month later we went to celebrate her birthday at her family's house after blowing the candles and giving her a beautiful white gold ring we basically were watching tv..and i just leaned to give her a kiss, her dad suddenly walked in..he was like "having fun?" we didn't even dare to answer when we went home her dad told her that its either me or him and now BOTH her parents think that we could no see each other her mom said "i love him, but if you guys stayed together you would of slept with him, which is not right", however we weren't gonna sleep together anytime soon..

NOW i cant even talk to her without her sneaking...I NEED TO APOLOGIZE TO HER DAD for not involving him and talking to him about it from the beginning COULD SOMEONE PLEASE WRITE ME a very nice apology letter..shes the love of my life and i don't think i could let go of her and i don't think its fair to be accused of something like that, im not with her just for sex..could anyone PLEASE help me..asap THANK YOU SO MUCH
