A small boy turned to his Aunt Mildred and said, "Wow, you're not pretty!"

His mother overheard the remark and was appalled. She took him aside and gave him a real telling-off before ordering him to go back out to say sorry to Aunt Mildred.

Suitably chastened, the boy went over and said quietly, "Aunt Mildred, I'm sorry you're not pretty."
