So if I was talking about how my friend ate a sandwich I'd say "That kid ate a sandwich!" instead of "That guy ate a sandwich!"?
I said they don't address each other as Guy. As in, directly talking to them. IE, "Shut up, Guy." It just doesn't work.
There's no need to be that hostile about it.
I have a bad tendency of jumping down peoples' throats when they say something wrong. ._.
