Never Cross a Woman, Particularly the Mother of The Bride

Jennifer's mother had found the PERFECT dress to wear and would be the best-dressed mother-of-the-bride ever.
A week later, Jennifer was horrified to learn that her father's new young wife had bought the exact same dress. Jennifer asked her to exchange it, but she refused.
"Absolutely not. I look like a million bucks in this dress, and I'm wearing it," she replied.
Jennifer told her mother who graciously said, "Never mind sweetheart. I'll get another dress. After all, it's your special day."
A few days later, they went shopping and did find another gorgeous dress. When they stopped for lunch, Jennifer asked her mother, "Aren't you going to return the other dress? You really don't have another occasion where you could wear it."
Her mother just smiled and replied, "Of course I do, dear. I'm wearing it to the rehearsal dinner the night before the wedding!
