It's not that the older you get, the more lonely you are, but the more books you read and the more complicated things you think. The world of uneducated people is very simple. I cherish those who cherish me. Those who dislike me, I abandon them. The world of literate people is much more complicated. Everyone wears a thick mask, and we never know whether the face of the person sitting opposite is real or a mask. So the longer we get along, the harder it is to make friends.
