What is in a Name?

I told my son to get in the car because we were going grocery shopping. He asked me if "the 5 brothers" could come, too. We only have a son and daughter, so I asked him who the five brothers were? He proceeded to introduce me to "the brothers". He said, "Mom, this is Ben, Micheal, Jack, Blooded-half, and me. We are the five brothers." You can imagine my horror when he named the fourth brother. I said, "Honey, I don't think I like the name Blooded-half." My son said, with his hands out to his side and his head shaking from side-to-side, "Mom, that's his name, you can't change a name." Ever since then, "Blooded-half" has been a part of our family. I often forget how horrible that name is until he introduces him to our pediatrician, or the cashier at the grocery store, or some unsuspecting parent. What is in a name, anyway?
