Dirt? A bruise? A burn?

Last week, I was playing with Elliott when I noticed something on his arm ...

How did he get such a patch of dirt on his arm? No ... I don't think it's dirt.

A bruise? No, too red-ish.

It looks just like a burn. How in the world did he get a burn and us not know? Ok, that doesn't make much sense ...


Oh! Ha. Got it ..... Self-imposed arm hickey.

Funny boy!
