absent I'm so sorry for the pain you're suffering because of your husband's illness. I lost my beloved husband to Covid in May 2020, and was lucky that he had a very kind Consultant, who allowed me to be with him as he died. I find a very real comfort in having some almost life sized canvases of him in some of our happiest moments, on my walls. I kiss him every morning and evening, and talk to him all day, and I believe and feel that he hears me. If doing the same sounds a good idea to you, I hope that when your husband's illness reaches its conclusion, you can find the comfort that I do, by doing the same. I'm so glad you encountered that lovely lady. Such kindness from strangers means so much: possibly more than they themselves will ever realise.
In the spirit of the original post; my joyous moment yesterday was taking the dogs to help me give my horses a carrots treat session, and having my very nervous oldest horse (he was terrified of people when he was sent to auction) come and give me a whuffly "kiss" and allow me to fuss over him for a while.
