Is NOBODY wrong in the post ? POST : Today was the birthday of a friend of my girlfriend and it was celebrated on a restaurant about 10 minutes from my home.
I bought a new knife a few days ago, I like knives, I know how to fight and since I live in a pretty dangerous area, I often go out with it to defend myself in case I need to.
I brought it for the birthday and my girlfriend noticed and was very mad at me for bringing it when I’m with her.

So, AITA?
