Here's another Oprah quote: “Take responsibility for your life, and get an education."

You should stop quoting someone who doesn't know proper usage of a comma. Or was that your comma?

[Savage Beast]

It was my comma. I'm sure Oprah knows better. Anyway, I think I used it correctly. Since the subject in the vocative case is you (understood), the sentence could be simple or compound; isn't that right? (It's been a long time since I studied college grammar.)

Maybe Oprah can tell us.

HEY, OPRAH! Are you reading this? What's the proper use of the comma in this case???
