Elie - Pee in the bed

I consider Elie to be completely potty trained, but he does still have occasional accidents. Sometimes if he's naked and playing with water he can't get to the toilet in time, and once in a while he still pees in the bed. I guess it's been a while since the last time, but last night was one. When he woke up and saw the pee, he said, "Yav (Yoav) pee." with all seriousness. When Yoav heard him say this, he laughed and said it wasn't his pee. So then Elie said, "Ima (me) pee." and stuck to that story ;) I don't think he was trying to hide anything; I think he just thought he would have remembered peeing in the bed if it was his...
