Could it be because the interactions you have with most people in general involves them feverishly staring into their smartphone and typing something into it for a majority of the time you are with them? I have some friends like this and it fucking pisses me off. Yes the occasional text is ok and expected these days…

I think it is important to note the difference between an introvert and someone who is shy. Approximately half the population is introverted—more males are introverted than females—and there is nothing wrong with that. Being shy, however, is being scared of interaction.
