Well, I dislike having to make eye contact at the best of times. It's so irritating when people demand your gaze, and after hours of complaining, you're forced to explain that, in actual fact, it's impossible to look someone in the eyes, because one can only focus on one eye at a time, and such a choice... Which one!?
In the end, you have to gape at the bridge of their nose, which is just silly, and I can't keep it up for more than a few minutes. Most of my sentences are addressed to walls and ceilings...
Now, add another four eyes... thats another four options, and three times as many reasons to be berated by your fellow man for insisting on minimal eye contact!
