Knock. Knock

Went to dinner at my sister's house. My niece kept asking me if I wanted to run a race with her. I politely declined, each time , explaining that I was having a baby and unable to run around with her. Eventually she became curious about the "baby". She was afraid at first to feel the baby kick. Then it became fun.

She pointed to my belly button and asked "is this the door for the baby"?

Priceless.
