OHGrandma is right. If DS watches any Nicholodian shows, the attitude shows up right away. Or is with certain friends. This has been the case since he was in preschool and continues now. He does not see the difference, but we do. I just say, that is how the characters on the shows talk to their parents, but it is not how you speak to us. Or if he has been with friends all day, I tell him that it's OK to talk to close friends that way, but not to adults. He did not get it at first, but I see how he switches back and forth pretty easily now.

I will say that sometimes DH and I do get a little sassy with each other too. So I will take some responsibility as one of those less than perfect role models.
