I was reminded of my days visiting my sister in Chicago. I recall buying my dad this 8x8 TV remote that we all thought would be perfect for him. He had problems seeing the numbers and he had a couple trigger fingers that made pushing the little buttons harder. But when he opened it at Christmas he was likek WTF? He did not appreciate my sister and my thoughtful gesture! You describe many parts of your story well, so the Holy grail is spread around in a good way.
