My grandson, a toddler on the go, and I, his grandfather with Parkinson's, have a closeness around matters of motion. He knows that I can't carry or lift him, so he climbs into my lap. It worries me that he might only think of me as "Papa on the couch." Yesterday, I got off the couch with difficulty. Before I knew it, my grandson came up behind me, placing his hands behind my knees. He helped me walk, using all of his 30 pounds to support me. I was in tears. What do children see, feel and understand? Everything. — Larry Zelnick
