My sister and MOH texted me last night, telling me she was summoned for jury duty the three days before my out-of-town wedding. I was really counting on having her here as of wednesday to help with last minute things - and that means she'd have to miss the bachelorette party and rehearsal, too! Any suggestions on how to get her out of it? I know she's postponed it once before because of an exam, but I don't know if they'll let her do it again. Help!
