New Grandpa

A few days ago I told Ben that Grandpa was coming to visit (my Father-in-law). Ben started thinking and I could see the little wheels turning in his head. He then said, "Grandma got a new Grandpa!?", (my Mother-in-law remarried just over a year ago, apparently this just dawned on Ben). He finished with, "I guess she didn't need the old one anymore!".
