I was close friends with someone for a number of years through high school but we drifted apart when we were older. Last contact we had there was a bit of a falling out and I said a couple of things I regret. I believe she blocked me on facebook and I no longer have her number so have never been able to apologise. Anyway I saw a few threads on here by a particular poster and they rang a bell. I looked at this person's posting history and there are numerous things which tally with what I know about her. I'm pretty confident it's her. Would it be wrong of me to contact her? It has been several years since we spoke but we used to be extremely close.
