This is a stupid story of my undergraduate.
When I was a undergraduate, I was a member of department of pharmaceutical science. I used to be called like 'regrettable guy' from my colleagues.
But now, I totally understand the reason why they named me like that.
It's a kind of jealous feeling. Actually, in my undergrad., I didn't need to take much time for learning. Also I didn't need to listen any pharmaceutical classes, 'just attend to sit those exams'. Nevertheless I got good results in exams everytime. Definately, It was incredible things for them. I saw them who struggle for passing exams. Therefore, they wanted to take me away into lower level that is same as their's via naming regrettable to me. In other words, they kept their peaceful mind by doing so.
