You have apparently done a good job with him and raised him with some morals. So he's still the child and will act like one but he wants his mom to be well - kind of virtuous. You are his mom.I see no friends in this house right now.
But yeah, I know. I can't embarrass him. (or I totally can, if he deserves it!)
However. ask him what it's like when his friends stay over and who they want to stay up superlate with them?
one hint. She's a mom! I bring the party with me!
