I went to the grocery store the other day and the Salvation Army man was there. He was standing by the long line of carts for people to use.
They were all jammed together so it was impossible to just pull one cart out.

He stopped ringing his bell and came over to help me - and he was just so darned nice about it.

When I left the store I remembered to put some money in the kettle and he was just as generous with his "God Bless You".
