/cgl/ - Cosplay & EGL

I just wanted to make a friend with a girl

>walking around dealers hall in cosplay
>was an idiot and had my prop sword and sheath on my back
>homestuck girl comes by and takes it out and tries to run
>chase her down and try to get it back from her
>after about 2 minutes of arguing she gives it back but flexes it as hard as she can so the paint on the blade chips and cracks, making it look awful
>call event security over, explain to them
>they say that since I have it back there isn't anything they can do about her trying to break my things or attempting to steal it
>she smugly walks off and I have to change out of cosplay for the rest of the weekend
I really really hate underage cosplayers, especially the homestuck/SU/Korra/Tumblr autism crowd
