I think there's also a fierce streak of independence* in there as well.
I'm in the danger age and health category and, having had a refusal from my chemist to deliver my medication, which I need this next week, I intend to catch a bus and go and pick it up myself. This, despite a note from my (much younger) neighbours offering any help I need, plus one of those leaflets through the door from another near neighbour ticking the shopping box. Both notes helped restore my faith in my fellow humans which has been on a steep downward slope since all this started.
I know I should take them up on their offers but I am not ill so why should I put them at risk rather than myself? They both have children. It doesn't feel right.
