S.S.
I brought my husband to my grammar school reunion and he had so much fun he is looking forward to it again this year coming up. So you just never know. If he is leaving it up to you, I think that is a husband's way of saying they aren't that interested but will go. If that's the case it will be you that will do the babysitting. Unless he is really excited and can't wait, too, perhaps he'd feel more comfortable at home.
