I have noticed that as you rise up in the festering lava pool of academia there are certain set stages in your career. These are illustrated by what happens when you go to conferences and meet people.
Stage 1 - You stare in awe at all the famous people who's text books and articles you have read.
Stage 2 - You go up to someone and say "Hi I'm John Smith" and they don't seem to care.
Stage 3 - You go up to someone and say "Hi I'm John Smith". They say "ah your John Smith!"
You are not sure why they have heard of you and your worried that it might have more to do with your bar antics than your science.
Stage 4 - You go up to someone and say "Hi I'm John Smith". They say "yes I know".
Stage 5 - You don't bother to introduce yourself because you assume people will know who are and/or you can't remember who you have and havn't met before and stage 4 is getting embarassing.
Stage 6 - Some first year PhD student comes up and says "Hi I'm Dave Jones" and you stare blankly at them while thinking "so what".
