Dead Mermaids?

Let me explain this title. We were getting ready to eat dinner and, as always, Shannon wanted to say the prayer. We relented, AGAIN, and she wanted to say it by herself which can turn out very odd! ANYHOO, Shannon is doing well and out of the blue says "and please bless us that we can see a dead mermaid"! WHAT THE HECK? Derek and I had the oddest faces on when she finished. We asked the girls what this was all about and Erin claims that one of her friends said she saw a dead mermaid. For starters, we had to explain that mermaids are mythical creatures...not real! Erin actually wanted to argue this point with us! We also had to talk about keeping our prayers reverent and it's not appropiate to ask for a dead mermaid let alone a live one! I tell you, I wonder where we went wrong sometimes! I didn't think we'd ever have to censure the girls' prayers!
