Does it annoy you when people text you just to talk and waste time but they dont have anything to talk about?

Absolutely. I think that is uncaring and rude.

Oh amazingly so, just like when they use LOL and you do not reply and they message you later asking why you stopped talking

Yeah but people learn pretty quickly not to bother doing that with me since I just won't keep the convo going if they have nothing to say

I'm with ya man. I don't mind it, however, if you text me with something vague like "Hey! What's up?" Its kind of a waste of time. Or one word responses! Those are the worst. Give me something to work with, yo!

I try to go on with it but then I run out of things to type and think "Now what?"

I don't mind. It's either the conversation stops, or it doesn't.
