Mom: Do you want to come to dinner tonight? Dad and I are going to Boston's. We're going to meet one of our old friends. His son is interested in dads "old line of work."
Me: Well it depends, how old is his son?
Dad: Junior or sophomore in college.
Me: oh.. college.
Mom: What? Thats only about 4 years.
Dad: Excuse me.
Mom: What? Thats the same difference between your parents, right?
Dad: What are you encouraging?
