Why don’t you keep in touch?
High school was a very unpleasant experience for me (although, to be fair, the cause of the unpleasantness was NOT my classmates). When I graduated, I was eager to put the whole affair behind me and move on to Beis Medrash and college.
By the time I was older and wiser, I had already lost touch with everyone and had no real way of getting a hold of anyone.
Every now and again, I google a name to see if anything pops up. In addition, it’s very easy to find my email address (the one associated with my real name, not my nom de blog) if you know my name. If any of them every googled my name and wanted to get in touch with me, I’ve made it very easy for them to do so.
