Wonders never cease

So I'm walking out of a Stop & Shop, and a woman is stopped right in front of the exit door. She removes her bags from her cart, and leaves the cart right where it was. This means if anyone happens to be coming in the entrance and someone wants to exit, one of them has to yield to get around the cart left by this self-important c#@t.
As long as I live I don't think I'll ever understand how someone can grow into an adult and have absolutely zero consideration for others. How does that happen? How do people go through life thinking they are all that matters in this world?
One of life's mysteries I guess.

I guess tolerance is conditional?

Tolerance for Islam? Tolerate this video.
