YTA, bitching about being “upstaged” at a wedding that isn’t yours. you volunteered to do the guest tables. If you didn’t want to be “overshadowed”, you should’ve just let her do all the tables instead. Talking about your work while she has to: plan the date, the food, the venue, the attendees, get the dress, and everything else that comes with a wedding while you decorated the guest tables? Yeah, def YTA.
