My brother has two grand daughters.One is eleven and the other one is eight. They were getting ready to go swimming. The eight year old goes up to "poppy" and says: Poppy, Megan can't go swimming. Poppy says "why not"? The eight year old says because she is having her comma. Her comma asked poppy. Do you mean her period? The eight year old said "yeah I knew it was one of those sentence things".
