You all know this old woman. The one who looks like she's had a hard life, and has enough of a glare to make sure that you realize it too. The one who will stare down some wiry young guy playing on his iphone until he realizes that there are no empty seats on the bus and guilt him into offering her his seat.
This is the woman that offered me her seat today. And the bus wasn't even full. I apparently have a delusional concept of how fatigued I look, because when this woman takes sympathy on you, you know you must look world weary.
