I think I am really getting old. Tonight I went to a bar, Bar None, in Yale Town with Pat and her friend, I found myself not really enjoying going to those places, I think the music is too noise and meaningless, the people there are doing nothing really interesting except maybe someone is trying to pick up someone. I felt tried and bored at 12a.m. already. I remember I used to go clubing quite alot in university days, and I did enjoy it. Now, I would rather go to a jazz bar or piano lounge with life performance. Why people like to hang out in the street at night? I can no longer understand it although I was part of them. I prefer to stay home to get some work done or catch up with my readings and writings. I always think myself is an extrovert but it seems I had became more like a typical introvert engineer.
