Purple Nightmares

The girls don't realize -- yet -- that I can hear them if I'm in our bedroom and they are talking in theirs. I've learned some interesting things about their classmates, but most conversations are mundane.
Yesterday the brunette twin said to her sister, "I had a bad dream last night. Someone broke into our house and stole all my purple clothes. Isn't that bad?"
The blond twin replied, "Sissy, people like colors other than purple. Purple is your favorite color but not everyone likes it."
The brunette twin said in her most horrified voice, "No, purple is the best color and someone stole all my purple clothes. What would I wear?"
