Pets DO make a difference! The waiting room attached to the Rad Tx room where my son was being zapped and where I waited for him, was regularly visited by a therapy dog. She was a beautiful collie and would only approach anyone after being invited. I'm not a "dog" person but when I saw her sitting a few feet away and looking at me with her gentle soulful eyes, I couldn't help but smile at her and she came over and sat by me for a few minutes. It really helped.
