So last month my dear grandmother passed away. (God rest her soul. Granny, I’ll never forget the innumerable ways that you made me a better person.)
When she had been brought home from the hospital and was on hospice care, she was unable to eat and drink normal food/water, so about all that we could do for her was to offer her a bit of water via a crushed up ice cube from time to time. She found it to be very comforting to just have the touch of moisture in her mouth, and it was certainly the least we could do.
