What do you think when someone is ignoring you?

Look at that person. What is (s)he doing? or maybe they have too much problems that they have to solve. Don't take it too seriously...unless if that person is doesn't like you, you may ask for what you have done wrong to that person...

I try to remember if I did anything to make them ignore me.

If I didn't, then I just act like I don't care & go on with my life.

I stop talking and if they notice I ignore them.

depends on who the someone is. if it's a close friend/family I'd want to know why. if it's someone I couldn't care less about then s c r e w them.

Stop talking to them, and when they try to apologize cause they want something from me, rip into them and leave them three new butt holes

Apparently they don't have to watch Dynasty to have an attitude

Punch them

i don't care if someone ignores me i don't care about anything i'm careless

I'm like; meh. Grow the f*ck up.

That they are wasting my time, either tell me what's wrong or stop acting like that.
