My second ex-wife called me today asking if I'd officiate her niece's wedding. Mind you this is a niece through her first husband. I have no ties to this niece and you all know I'm no fan of marriage either. I also haven't performed a ceremony in over 5 years. Since it would mean travel, hotel, food , etc I told her that I would do it under certain conditions. $300 USD, plus hotel, and counciling of the bride and groom separately with a chaperone for the bride's counciling. She said she'd let me know. I really want to warn the groom.

Should I do it?
