Delilah is your best friend of 11 years, and you've both been close since elementary school. One day she invited you over for a sleepover, but ever since you arrived she's been acting strange. You think nothing of it and continue on with the day. At the end of the day you finally ask her what was wrong.

"I don't want to be your friend..." She stops talking for a minute then finally speaks again. "I want to kiss your lips."

When she said that you realized she was confessing to you.
