So I always believed I was fairly popular in my engg college days. What will all that enthusiasm of IEEE comittees, Student Development Forum, DAnce competition and personality contests!
I met my brother's friend who was 3 years junior to me. When he was in first year, I was in final year. And I was too happy to meet a junior. I didn't know him but you are really not supposed to know someone so junior. But the first thing he asked on seeing me was:"So which college did you study in?"
We existed in same space and were part of the same committees and he had no idea who I was. I was so completely wiped out of memory of my college. That too in just 3 years :(.
