"I don't know.."

"I don't know" are three words that drive me crazy! Sweet face Tasha (sweet as seen above) came crying to the kitchen last night after she should have been in bed....she was not so sweet faced then....more pitiful me faced! Why? She said Mercedez hit her. Why did Mercedez hit her? The first words out of her mouth..."I don't know". ugh! Mercedez room is a long way from Tashas. Mercedez almost never hits....which leads the question what would provoke her? Obviously Tasha! Or just in this case. I can ask any injured person in this house "why" and the answer is always "I don't know". And I don't know why...lol!
