What are your thoughts on messaging a girl on Facebook that I know and went to high school with?

I was thinking of messaging this girl on Facebook. I used to talk to her in high school. We would walk out of class that we had together talking. She was always a sweetheart. But we haven’t talked since high school about fifteen years ago. We are friends on Facebook. What I’m hoping out of this was catching up. If it turned out to dating great but I’m more interested in just catching up. What are your thoughts.
