People being protective of their items also makes me angry, a reflection

I'd like to start off by saying I know this is completely irrational. I just wanted to rant cause I was reading a fanfic and a part made me mad and it made me realize something about myself. I really hate it when people are protective are their material items. I get it if their fragile, but when someone says they don't want people touching their stuff it always makes me angry, and I feel so bad cause it's really a simple boundary. One I would never cross on purpose, but one that for some reason just makes something stir inside of me. Maybe I just don't like the feeling of being in the wrong, but even when I'm not involved I feel this way. Maybe it's cause I don't have find much value in material items. If I go to a concert, it's not for the music, it's cause the people, I don't find much difference of listening to an artist in person or online. I like making collections but I'm not attached to the items, I'm just attached to the franchise. This isn't all true I guess, I do find some value in it, but not very much. Or maybe I've just grown uncomfortable with the idea of someone having boundaries cause mine were never respected.  

Reflecting so I can better myself and using this blog to do so! :D
