Kadyn and Graysen were playing trains beside me.
Kadyn: Hey! Mama! Look!
He puts two pieces of track together, grabs the airplane, drives it down the 2 piece tracks and TAKE OFF!
Mama: Very cool. Is that a runway you built?
Kadyn: I guess. *puzzled look* But Mama?
Kadyn: Planes can't run. *small pause* They don't have any feet.
Mama: *giggling* I know, bud. But planes take off and land on something called a runway. It's just a long strip of road but it's called a runway.
Kadyn, very matter-of-factly: Well planes still can't run. Cause they don't have feet.
