Backhanded Compliments

This morning Charlie was hanging out with me in the bathroom while I got ready.  As I stepped into the shower, he said, "Mummy, your bum is more comfortable."
"Why is that, Charlie?"
"Your bum is more comfortable because it's bigger."
"To sit on?"
"For piggy back rides.  It more comfortable for piggy back rides."
"More comfortable than Daddy's?"
"Yes, your bum is more comfortable than Daddy's for piggy back rides."
Ha.  Take that, Sweetie!
