hey guys, I know this is specific but I'm kinda desperate.

So I know this cute girl from high school, we never were friendly with each other (or really even talked to each other), but we had mutual friends. I think she thought I was funny because I could make her friends laugh, though I was a fat bitch in HS and never thought to talk to her.

fast forward to now, 5 years later, we're friends on social media and I've lost about 40lbs in the last 6 months so I'm a little more active in posting pics and whatnot. she's usually one of the first people to watch my Ig stories (which is in itself meaningless) but she also liked my new Fb photo 2 weeks after i posted it, and an Ig pic that was of me and my coworkers (she was sort of the only person to like it that is not a coworker or my best friend)

I know I'm maybe reading too much into silly social media behaviour but I'm going to message her anyways, either on Fb or Ig (was leaning towards Ig).

don't know what to say though, maybe something like the following:

"hey how are you? was just talking about HS with some friends last night...wish we crossed paths more back then."

and then see what she says and go from there

thoughts?
