The creepiest thing that I head a kid say

A couple months ago I was hanging out with my friends at one of my friends apartment complex and we decided to go outside at the playground area. Then little kids came out and they were saying "Hey! Im better then you!!" and "Yeah? I don't fucking care!" And we were like WTF have these little kids became.. Then this little kid came running after them with an axe yelling "Im going to kill you!!" And that was terrifying... Soon one of my boy best friends ran after him, took the axe and threw it in the bushes.
