The setting was in a testing room at a high school. There was this girl who was assigned to a seat next to me. The proctor didn’t really know what he was doing so we just gave some weird looks to each other because it was just really funny. During the first break, i asked for her name and which school she came from and then our next portion of the test started. When testing was done, I asked where are you going she said "home". I asked if I could walk with her over to the parking lot of the school, she was super surprised I said that and her friend just started laughing, then she asked me to repeat my statement then she said yes. I started to get to know her a bit more on the way to the parking lot. At a high point, I asked for her Snapchat and then we parted ways. Later, I found out she gave me a fake username, I then just laughed it off, feeling satisfied with what I did, and then just went on with my day. Is there any advice you guys have for me or is there anything to be learned?

EDIT 1: Parking lot of the school and not to her house lol
