Zoey: "Mom, was there t.v. when grandpa was a kid"
Me: "Yep."
Zoey: "Grandpa said they didn't have a t.v. when he was a kid."
Me: "Well, t.v.s were pretty new then and not everybody had them like nowadays. Also, grandpa's family was pretty poor so they got a t.v. much later than lots of people."
Zoey: "Is that why he watches SO MUCH t.v. now?"
