Other mother: "What sign is Saskia?"

Me: "Pardon?"

"What's her astrological sign?"

"I have no idea."

"What!? You don't know your daughter's sign?"

"No. I don't know any of my kids' signs."

"I can't believe you don't know that! My daughter is an Aries, so she's really independent. And my son's sociable and avoids conflict, because he's a Libra."

"Do you know their blood types?"

"No. I don't. Now tell me your kids' birth dates."
