OML I was Chara too. Except my friend Nevaeh was Sans (although she's a girl) and my other friend Alisha was Frisk. We just sang. Although when I've cosplayed with a few of my friends as Frisk, I went with two other friends who went as Chara and Sans. I walk away for two seconds and they just start fighting. We were in town too. xD I just come back and I'm like "Really guys?" .-.
