Like several others here, I don't have any children myself. It works out well though, since I've never gotten married either.
But, I have 8 nieces & nephews, 10 great nieces & nephews and any day now will have a great-great niece. (I have to remind myself that it's okay - I've been an aunt since I was 9 years old)
I also used to work at a daycare. So, I've had a lot of kids in my life.
A little boy at the daycare (he wasn't quite 2 years old) was very enamored with basketball. That's about all he would talk about. One day at snack time, he looked at me and said (again) "See the basketball." I said, "No, I don't see it. Where's the basketball?" He said, "See Grandma?" I said, "No, where's Grandma?" He replied with, "In the middle playing basketball!" Of course, when his mom came to pick him up, I had to tell her the crazy thing he said. She started laughing and informed me that Grandma was on a senior citizen basketball team. They had played the night before and she took her grandson with her. And what position did Grandma play?? Center. The kid knew exactly what he was talking about. I was just too stupid to understand.
