My best friend is going to a wedding today. She RSVP'd w/a plus one (she had a boyfriend at the time and doesn't now) so she asked if I'd want to go as her date. I said yes because who doesn't want to go to a wedding! But now I'm wondering if it's tacky, lol. I mean I know the groom (we all went to high school together) and they already paid for the extra plate. Is it ok that I go or should I stay home?
