I have already found it annoying that people who initiate conversation with me, then use their phones during that conversation, to be annoying. I have also been somewhat creeped out by people who can’t seem to get enough of their own photos. It’s like being your own paparazzi. You love yourself in a celebrity-like way, as well as tapping into the zeal of those who chase that celeb around. Narcissism never had it so good.
