What kind of a bridal shower lasts several hours? I can’t imagine spending more than two hours at one.
I would never even think as you are about any difference in age between me and these women, especially not in the capacity of being at a bridal shower. You aren’t talking about a bachelorette party, right? Even then, you are not so much older that I’d ever feel like a fish out of water. Also, I’ve seen so many of those where the older generation of women join in at the strip club and everyone has a good time.
