Ugh it's terrible when you are making plans (kinda what @Nath said) but only one person isn't replying, and he's the one that wanted to do something.

I don't really mind when they take a long time, however if it's important to them, me, or someone else that is important to us that we have to discuss about, like an assignment for example then it becomes annoying.

I think it's worse when they drop out of a conversation, instead of just not answering the moment you start one.

And why is this in the bragging section?

I had this with a friend on fb before, he was telling me about how he saw my message asking about some hw, and he didn't want to open it as he knew I would read it says read and he cba to reply, then he accidently opened it lol
