Twenty Years

Me: So, my mom was saying my nephew and his new girlfriend are rushing into marriage. They haven't been together a whole year and they're already talking about tying the knot. Mom said they’ll end up married for twenty years then divorce.
Austin: Twenty years isn’t bad in today’s society.
Me: Are you telling me we’re only going to be married twenty years? We’ve got fourteen years left?
Austin: That’s generous.
