Dear Annie: I work at a school as a teacher and have struggled over the years with how cliquey the other teachers have been. Shortly after I started there, the pandemic happened, and many people friended each other on Facebook. Because that was the only source for a sense of community as we went through those first few dark months, I accepted many of the friend requests, and that felt good. However, a couple of years later I couldn’t help but notice how people commented on each other’s posts and tagged each other like they were friends in real life but never with me.
