Q. My son is a senior and was invited to the junior prom by a friend. What are his financial responsibilities aside from showing up in a tux with a corsage?
A. His financial responsibilities are theirs, other than what you listed, the tuxedo and the corsage. She asked him, and therefore the costs associated with the prom are hers. If they participate in a post-prom party, he may offer to share the expenses or even pick them up, but the prom costs are hers.
