CHANGING A DIAPER
1) cloth subway seats
2) the lady beside her reading a piece of paper.
(I was one of the only ones who appeared to want to barf at the sound and smell of this lady wet-wiping a poopy butt in a confined area with no absolutely no fresh air. If this had happened in NYC, the other subway riders would shamed her silly with their death stares or unsolicited opinions on the matter)
