I used to have a relatively good friend whom I knew for years, but after moving, I am somehow unable to figure out what he is thinking per se. As a buddy, I used to believe that that we were best friends, but after being estranged over some ethical issues which we could not agree over, I barely started talking again. I always get this strange feeling as if I am talking to someone who takes personal offence at some of my words or if not, could get a chip off his shoulders and hence, my concern is, for friends whom you now only manage to talk to online, how would you even be able to know if they are pissed at something you wrote or said?
