Is it normal that my friend likes to collect knives?
I need to specify that not only does he like knives, but everything that has a blade. He is a normal guy, although he is kind of sad sometimes, and often doesn’t speak a lot. I just hope he doesn’t do some dumb sh** such as ending his own life or killing somebody (I know I am going too far with my thoughts but I really care for him, since he has been my first actual friend).
