My husband and I were waiting in line at Express on Monday and a mom with a baby and 3 or 4 year old was in front of us. The mom was letting the baby crawl around and the older sister was entertaining him. The mom was making a return so she was at the register for a long time. Eventually the girl started talking to me about her baby brother. I told her she was a good big sister for helping her mom. Then she asked "Do you have any kids?" I told her not yet, but one day. She told me "You can have kids when you get married." Lol. That was totally unexpected!
