What's a Bachelor's Degree?

The following conversation happened in my car yesterday. The 8 year old boy I watch was bragging that his mother (who happens to be divorced), is graduating tonight with her Bachelor's degree. He was so proud of her and he had every right. Then my daughter asked him what a Bachelor's Degree was.

His answer:

"Someone who goes to school without a husband."

His poor mom...she deserves so much more credit for her accomplishment! lol
