My family became family friends with a girl who used to go to my high school. I work at a tutoring center for my dad and her and her brother come in to help sometimes. One day I was looking at her while walking by and she caressed the desk with her hand after making eye contact and smiling. Then she invited me and my family over and talked to me a lot there(she came out her rom later than her family wearing makeup). I was kind of shy and nervous so it was kind of awkward. She then asked if we could go to the movies. Idk if she meant with me and me and my family. I dmed her next day and she gave me her number. How should i respond?
