Everyone has a different way of saying goodbye. I'm sure most of you don't just say "goodbye" when you're saying goodbye to someone. So AG, how do you say it?
I'll say bye, goodbye, or I'll disappear. If I'm not talking to someone in the last 10 seconds I'll likely just disappear. I'm not very good at knowing what to say when I meet people or when I leave them. So I mostly just appear and disappear silently unless someone talks to me first.
I tend to do that too. Usually people don't tend to notice, but had they noticed me in the first place I wouldn't need to silently walk away in the first place.
