On a hot and humid Tuesday in August, my wife and I walked back to our car in the Yawkey parking garage after a long day of a chemotherapy treatment at Mass General Hospital.  The level was empty, except for my car, and across the way, lying face down on a parking space line was a pink stuffed pig.  I rushed over to pick up the dropped toy, my heart broken for some child going through a treatment, or accompanying a parent doing the same, and I began a campaign to reunite the pig with its owner.
