Look What My Son Did – Is This Okay? [PICS]

I went to pick up my son from his summer camp today. When I walked in and he came over to me and proudly showed me what he had done. I nearly fell over.. And as a Dad, I was a bit shocked! What do you think; am I overreacting because he's only almost 5? Is this okay?!? I'm not so sure!

I got a little bit mad and wanted to take it off right away.Was that too much? He liked it so much, I couldn't deny that adorable face so I let him keep it on for another day.
