Brother [talking about the new cat]: Why did Miguel sire her? Couldn't he have sired a dog?

Me:... 0_0 Do you know what "sire" means...?

Brother: Of course!

Me: Okay... What does it mean?

Brother: Uh...

Me: I'm going to tell you a sentence, and hopefully you'll understand the meaning from it. "Your father sired you."

Brother: Oh.... 0_0

Me: [facepalm]
