Yep I experienced that before. We were closed friends then I told her I like her. It's kind of a joke when I told her I like her its like this "I Lab You _ _ _". We were just laughing then I got attracted to her. She doesn't know that I actually like her so I just hid it then at the last day of school we wrote who r crushes on the board and I wrote her name. So she knows that I used to liked her. We're still friends though. But I dont fancy her anymore.
