Meh. Moms have enough guilt. I think you should let yourself off that particular hook!
I think some of it is just the specifcs of how you push him to do it. "You're going, and that's final!" wouldn't be my choice. (Not that it would be your choice either!) "Let's give it a try! I really think you'll love it," would be more where I'd take it.
But if he gets surly about it, I'm not sure I'd actually force him to do it. If he decides he won't enjoy himself, then he won't, no matter how much fun it is. What's the point in that?
