They are away on a little vacation right now. However, before they left, they wanted to know when I was going to prep for another colonoscopy so my DH could take them out for pizza again.
I really do think it's funny. It's just that they wouldn't say anything in front of me. Their mother, my DD, is the one who just graduated with her nursing degree. She explained the whole thing to them and why it's necessary.
They just don't want to hurt my feelings or embarrass me. They keep asking my DH and their mother when I'm going to have another one.
