A close friend of mine is getting married out of state in two weeks. I has planned on attending and already rsvp'd. However, due to personal matter my husband and I can no longer go. I plan on contacting her tomorrow to tell her this. However, I'm worried about the money she may lose because of my changed RSVP. In a previous conversation she told me the caterers were not flexible with head counts and still charge full price plus a fee for last minute changes. I was wondering if I should offer to pay her for money she'll lose because of my inability to attend now.
However, I'm wondering if that's rude.
