Chloe: Why isn't there a Sister's Day, Mom? We need to have a Sister's Day.
Me: Hmmm. I don't know why there isn't a Sister's Day. Maybe we could have our own.
Chloe: No, I think we should just have our birthdays be our special day. We don't need to have a Sister's Day.
Me: Okay. That's a good idea.
Chloe: Besides, everyone will be a mother or a father when they grow up, so they'll get to have Mother's Day and Father's Day when they have kids, right?
Me: Yes, most people will, you're right.
Chloe: Well, they have to choose to be a mom or a dad. If they choose that they don't want to be, they just have to be a doctor or a dentist or something.
