"But you're still pretty"

One day during my senior year of high school, I woke up late for school and came in with no eye makeup on. A girl who sat in front of me in class said, "You're not wearing any makeup?" I said no, and she replied, "But you're still pretty." 

She said it with such disbelief and question in her voice, like she couldn't understand why I wasn't ugly. 

It made me feel so awkward and uncomfortable. Seven years later it still comes to my mind.
