"Play with toys, NOT food!"

About a month ago my extended family got together for my Grandma's 89th birthday.  When it was time for us to go home 'Middle Sister' wanted to take a piece of cake with her.  Since she hadn't had any I got her a piece.  When she had eaten all she wanted the bowl of leftover cake somehow ended up with 'Little Sister' who did this with it.  Don't ask me what possessed her.  Her Mother was not pleased.
