people with generous spirits

I admire people who have generous spirits, those who always seem to be thinking of someone else.  On Mondays I'm one of a group of 10 volunteers who tutor children from South Wayne Elementary School.  My charge is a delightful fourth grade girl.  Today one of the volunteers, a retired teacher and principal, spent almost the whole period in a group activity with all of the children.  She had just come back from a few weeks in Florida and showed the kids pictures of the beach on her cell phone, read them a book about shells, showed them, let them feel, white sand from the beach, showed them four different kinds of shells and let them take turns feeling them.  Then, just when I thought she was finishing up, and I was full of admiration for what she had done - she really held their interest - she gave them each their own little box of white sand with four shells in it, plus a piece of foil to spread the sand as she had demonstrated, and handouts explaining what kinds of shells they were. My little girl was delighted and we spent the last few minutes of the class admiring her shells and writing words in the sand.  I hope the teacher who did this appreciates what a fine thing she did.  I'm pretty sure several, if not all, of these children have never seen a beach.  Now they have a new insight into a really different part of our country. So kudos to this generous spirited person.
