My friend invites a couple of her friends to a game café (I was invited). We (my friend, her guy friend, & I) start walking home and I check my gps to make sure I get home the right way. Next I feel that he pushed me with his bag and I turn around and he pretends it wasn’t him. I return him the shove he gave me and he says “oh you wanna fight?” I look him seriously and I say “ok let’s go I’m not playing games.” He backs down and is surprised to my reaction. I told him I barely know him for him to start getting into my personal space. And he says I overreacted but you clearly aren’t going to approach someone you barely know not knowing how they’re going to respon. It could’ve been worst (I cussed him out and was ready to square up).
