Bathtime

Tonight after dinner, I started a bath for Kaitlyn and went downstairs to finish up dishes before washing her hair. (Yes, I know this can be dangerous.) Trace went in to check on her and as he opened the door she said, "Get out of here!". He asked her why and she said, "because, you can't see my business!" First.......when did this start and second.......when did she start having "business"?!!!
