I love that quote from The Velveteen Rabbit. It's maybe my favorite quote.

I notice now that I easily accept help. The other night at a pub a young woman at a neighboring table retrieved my bill and credit card from the floor where I had dropped them so quickly a didn't have time to blink, never mind protest that I was quite capable of getting them myself thank you. So I thanked her and added, "You're very quick."

There is not enough kindness in the world so why not allow kind people the satisfaction of giving up their bus seat for me?
