I used to, and it was because I was convinced that nobody wanted to talk to me... so I wouldn't say anything to most people unless they said hi first. which was really lame, because what if I had something to say?

lol, it's nice to have someone IM
you, but that goes both ways.
haha I looked back over this, and that was nott the point, clearly ^^
with people i haven't talked to in a while, i ask questions like what's new, what've you been up to, are you still doing this/that, how's so-and-so, la di da. how's this and that (new school, or new job or new anything), and if the convo gets super slow or traffic-jammy, i say 'well, it was nice talking to you again

i thought i'd say hi, we haven't seen each other/chatted in ages. i've gotta go for a bit though, so ttyl' which means the convo is over, unless they want to start it up again... and i don't feel like i have to log off or look rude when i end with that xD
