I've done the first but not the second. However I have thought why would they do that if they didn't want to talk? then I delete them after a week if I don't get a message from them.
I like the people who add you... ask you how old you are... if you are a boy or girl... and then you give them what they dont want to hear and they never talk or respond to you again. haha
Guilty..but I do it for a reason. It's not to say that I don't want to talk to them, I'm just horrible at starting conversations. Plus, I'm a little irritated that they added me just to add me. For the most part, I don't care. I just wish they would start a conversation.
