A great unknown line about airports

I did not publish a great unknown line for a while and my brother, who is currently traveling on holidays, gave one recently on Facebook (which seems to be the database of my great unknown lines now, I will try to find other sources). Here it is: "I always lose a bit of faith in mankind when I go through an airport." It does express the helplessness one feels in such a place, in a nutshell. In some airports more than in others.
