"i like you!"

O.O! The randomest thing happened to me yesterday. I was walking out of PE to my fourth, when this mentally challenged girl walks up in front of me. She turns around and says, "Hey!". Sure enough, I said, "Hey...". Then we start walking again and again she turns around and says, "I like you!", and then I say.. "Oh.. okay..." Then she turned back around and walk. Again, she says, "I like you." I felt so awkward at the time haha. So I just continue to walk as she turns around one last time to say, "I have a boyfriend." By this time I was running lol. But that's what happened yesterday.. goodness.. lol. Why do I always have experiences with mentally challenged kids? First the ice cream.. now this..
