I'm so pleased that you're getting some of the help that you need GG. It's also lovely that you appreciate the people that are helping and show your appreciation. All too often workers that come to our homes are taken for granted. We have always made sure that any workmen at our home are made welcome, given plenty of drinks (and access to the toilet), and food when necessary. We once had a crew of half a dozen rendering the gable end of our house, purely because they had time between contracts so the whole team turned up. I asked what time they were stopping for their lunch so that I could have their drinks ready. They said they weren't stopping so I asked if anyone would be offended by sausage and bacon, they all said no, but looked puzzled, until at lunch time I took out a couple of trays loaded with sausage, bacon, eggs, sliced bread and sauces and told them to help themselves. I'm sure that people are glad to come to help you because you treat them with respect, as they will you.
It must be a relief for you to know that your hubby doesn't have to contend with the stairs any longer.
