I have not really had too many hobbies when growing up. I did collect stamps for a while when I was really young but it was mostly done by my uncle and gave to me. I had some really nice and rare stamps. To top it off I also knew someone who was really into stamp collection and I was learning some of the history of some of my rare stamps.
Unfortunately, before I really got into it a classmate of mine stole the whole collection. I never really confronted him. I guess he knew that I would not, which is probably why he dared steal them in the first place.
Anyway, I did later get into listening to music, which led me to collecting mixed tapes (it was really difficult to get the actual tapes or records back then). And later yet I got into reading and collecting books.
