I am an undergraduate student majoring Math/Physics. Well, basically, I am very much into learning so I think about Math/Physics all the time. Even on Friday and Weekends, I usually stay at home and study. One of my friends tells me to go out and have some fun, but I simply do not know how or what he means by fun. Should I just go see a movie? or just chill out at some random place? Well, the point is, I simply do not find socializing and doing nothing very enjoyable. It seems that not many people have the same interest as I do, and as a result, I am often isolated from my classmates--not because they don't like me, but simply because I do not know how to approach them or start a discussion. Basically, I do not have many friends who I can talk to and socialize with. So, does anyone else have similar experience? or do I have some sort of problems?
