Y’know, I’m not certain that a wedding is a good first date (or one of the first few dates) anyway. Witness:
Bill, a friend of ours, took a new girlfriend to one of our friend’s weddings. They’d been dating casually for a while, but not hugely long, and she was looking to take it to the next level. Since Bill was a close friend of the groom, and since Bill’s parents were there, she thought that this meant that Bill was of like mind. After all, she’s meeting his parents and everything! Bill, not being as communicative as perhaps one should be in a relationship, was not of like mind. Matter of fact, Bill told some of his friends that he was going to break it off with her after the wedding. I don’t know any more of the details, but if I were her, I’d have been furious.
I think that weddings have the possibility of sending all sorts of the wrong messages for early relationships. Too much chance for misunderstandings. I’d go stag instead and have a great time. I’m certain you’ll be able to pull it off.
