That was funny
It reminded me when my daughter was seven and my son was five. They came running in to tell me they had a surprise for me. I went outside to find they had used there crayons on my car to make it look nice. I was pissed but what can you do with your little ones looking up at you expecting you to be happy with what they did for you. I told them it was great but don't do it again because it's bad for the crayons, they should only be used on papper.
