I recently began a job and a few other people started with me. Yesterday, they became Facebook friends with some of the people at the store we work at. So, I sent a friend request to them too and they didn't accept it, even though they added the other people who started with me. They have no connection outside of Facebook and hardly know them. So, why would they accept requests from the other new people and not me? I find it very rude and a quite offended by it. What is the deal with this? Why are they being jerks?
