Shouldn't You Be in School?

"Shouldn't you be in school?"

I remember hearing this question many times growing up.  Whether it was at a fast food restaurant, bank, grocery store, etc, I heard it pretty much everywhere I went.  When I was in grade school, my siblings and I thought it would be humorous if we invented crazy stories as to why we were not in school.  Our ideas ranged form not knowing how to speak English to how we were recent college graduates.  We would plot out exactly what we would say and rehearse it in the car during our trips.  My parents though, were not as amused by our discussion and refused to collaborate with us.
