When I was young, I rarely left the house besides for school. I spent a lot of time alone had a lot of free time. I used my free time to collect things: stickers, rocks (I'm not joking, my mother threw them out when she found out her closet was filled with rocks), rubber bands, Pokemon cards, and many more things. I wonder if any INTPs have any big collection of stuff that they've accumulated over the years? Any collectors?
