A couple was getting married, and it was only three days before the wedding. The bride calls her mother with some bad news. "Mom," she says, "I just found out that my fiance's mother has bought the exact same dress as you to wear to the wedding."
The bride's mother thinks for a minute. "Don't worry," she tells her daughter. "I'll just go and buy another dress to wear to the ceremony."
"But mother," says the bride, "that dress cost a fortune. What will you do with it? It's such a waste not to use it."
"Who said I won't use it?" her mother asked. "I'll just wear it to the rehearsal dinner."
