there will probably come a time when this sort of thing will be taken out of our hands. Maybe a good thing to do would be to bang on to the friend the importance of meticulous hand hygiene, not touching anything unless you have disinfected your hands and not getting close to people, so that if she does go out the risk is reduced, disinfecting doorknobs in and out, bin handles, post.....if the friend can be persuaded to cut down on trips out, maybe at first to once a day, could you promise something that would be fun for both of you, not sure what that is for both of you obviously. Or ask local good neighbours who would not pander to anyone's unreasonable requests. My MIL was like the mother, she would send my ex out multiple times a day for things she had forgotten [pre cv] and his feelings about this were mixed. At once he was annoyed about needing to go out, and didn't want to upset her by saying hed go once a day unless medically necessary, but he also liked the excuse to step away from the situation even if it was just to pop to the shop, basically, he was angry that his freedom to go out for a long walk to places he wanted to, was incompatible with the caring responsibilities. He could have called in respite care, which would have benefited his parents when he was not there, and which they were to a certain extent entitled to and had a reasonable break himself, but some people will not think reasonably sometimes, just to mention that sometimes people have lots of odd reasons behind their unreasonableness
