New! Sisterly Advice: Wedding day blues

Everything is under control ? dresses, flowers, caterers, etc. ? except for one thing: my best friend, ?Alice,? expects me to have her four-year-old son, ?Patrick,? in my wedding party as the ring bearer. Even though he?s cute and smart and occasionally really sweet, when you put him in front of company, he?s a holy terror. Not only does this kid throw major tantrums, but the parents don?t really discipline him. I don?t want the biggest day of my life preceeded by a floor show, but my friend is not going to take no for an answer. What should I do?
Signed,
Maura
