Smile and see how they respond. A lot like joking around, smiling at someone will usually produce a response. If the person likes you, they are certain to smile back. If the person doesn’t like you, they’re more likely to not smile back. Consider these things when “reading into” a smile:
- A person could simply be caught off guard by your smile. They would love to smile back at you, but yours was so unexpected that they didn’t know how to react.
- A person may choose not to smile even if they like you. Pretty much, they are convinced that you don’t like them, and so they don’t want to show you their feelings because they don’t want to deal with the rejection.
