I am an employer in the Chicago area. My nephew in Indiana is in need of a kidney transplant. My nanny had offered to get tested to see if she was a donor match. I know she did and was not a match. What I did not know is that over the past two weeks, she has had her sisters, cousins, aunts and other nannies get similarly tested. She has driven people in for testing and given other's subway fair. She told me none of this. Needless to say, I was reduced to tears. Is there anyway to show my appreciation to her for this? I was thinking rather than money or a gift certificate that I would get her a piece of jewelry, a necklace? I would appreciate any suggestions or ideas.
