Kids’ Embarassing Questions

Sometimes, we adults think we know all but when our kids challenge us with some mind blowing questions, what do we say???  Really, what are the embarrassing questions your son, daughter, niece or nephew has ever asked you? Just last week, I went to pick my 5 years old niece from school and on our way to the gate alongside other mommies and daddies taking their kids home, she told me: "I saw a woman with a BIIIIIIIG breast! What is inside? " Gosh!!! I had to look around first to be sure passers- by did'nt hear that. But before i could give an answer, she started guessing: "Milk and blood mixed together?" I said no. Fat and milk. Immediately it became a debate as she argued it was milk and blood that was there. It became so emarrasing and disgusting that i just kept my mouth shut.
There was just another time she was asking her VERY BRILLIANT AND ENLIGHTENED DAD what the eye lashes were for. I saw him thrown off balance for a few seconds and you wouldnt believe it, he couldnt give her a reasonable answer. We just laughed over it as he realized he never thought of that for one day. I later told her it was there to protect the eyes from dirt and dust!
You just wonder how they think up things,  Lets hear more please!
