Dear Prudence,
My sister, “Beatrice,” thinks she’s a great singer. The reality is that she sets off car alarms and makes nearby dogs howl with her voice. I’m getting married in August, and Beatrice has been lobbying my fiancé and me to let her sing at the wedding. When I told her no, she threw a huge tantrum and dragged our parents into it. She’s their precious golden child, and now I’m getting it from all sides.
I really don’t want the occasion to be marred or to have my sister humiliate herself in front of everyone, but if I stand my ground, I’ll never hear the end of it. My fiancé says to let her do it, and we can always tell people she was drunk. At this point, is that all I can really do?
