The long and the short of it

A few weeks back, my four year old son was talking to my mother in law about my dad (who is 6'5") and my mom, (who is 5'1"). She was saying how nice they are and how nice it is that they get to travel up here for free on Southwest Airlines (my dad once worked for them). Wyatt responded by saying, "Yes, otherwise we'd never get to see the tall guy and the short gal."
