Wow, I can't believe an elementary-school kid would be that cruel. I have a feeling he's heard relatives talk that way about someone in his family. I know it would be hard not to take it personally, but seriously, he doesn't really know you and your circumstances.

Alas, he did hit a sore spot with you. If you can shrug it off, then he won't be able to get his jollies. (I know--easier said than done.) You know why you're doing what you're doing. And not everyone needs a college degree. I know this statement sounds mean, but just because people have a piece of paper from a college doesn't mean they're very intelligent--and some of the smartest people I know don't have college degrees!
