DD (5 1/2) brought home an AMAZING picture she'd done today, picture of a girl walking a dog, was a really really good picture and she had also cut out the girl and stuck her on the picture which is a huge achievement for dd as she has fine motor issues and can't use scissors very well. The picture really was excellent, looked like someone much older had done it [boast]
So I gushed about it, told her how good it was, how proud I was of her and told her I was going to buy a frame and put it up.
Went back in kitchen 5 mins later and she had drawn speech bubbles coming out of the girl and dog's mouths, written a list of names (her teachers, friends, mummy, daddy etc) all down one side and generally filled every spare bit of paper with doodles.
Was so disappointed. And I told her she had RUINED it 
She has and it does look shit now, you can't see how good the original picture is because it's all covered in crap but I have really upset her, she went upstairs and has just brought me a note that says "sorry mummy i thought you'd like my good writting" with a picture of a cross mummy brandishing ruined picture and little girl crying
