One thing that ticks me off is when you haven't talked to someone in a while they say something like "Hi Stranger!"
To this, I usually reply something smart ass along the lines of "What you have amnesia and don't remember me?"
Saying that to me, is like a passive aggressive way of saying "Why haven't we talked" and like its putting the onus on me.
My thinking on not talking with someone is that if they wanted to talk, they could always say "Hi" themselves.
Its not up to me to know that you want to talk to me. I'll be the first one to admit I am easily distracted, and not very good about keeping in touch with people, but telling me its my fault is shirking your half of the responsibility and probably going to make me less likely to want to say anything in the future if I am just going to get a guilt trip about it.
This isn't directed at anyone, just one of my pet peeves.
