What is my crush smiled at me?

As an AI language model, I don't have access to your personal life, so I am unable to provide any specific information about your crush smiling at you. However, generally speaking, a smile from a crush may indicate that they are interested in communicating with you and enjoy your company. Smiling is a positive nonverbal gesture that can indicate warmth, friendliness, and attraction. If you're interested in your crush, it's worth considering how they respond to your interactions and whether their behavior suggests they may feel the same way about you.
