Saturday: Apart from Mrs P, zero interactions
Sunday: Ditto (about Mrs P), spoke to neighbour briefly through the medium of the hedge at a range of about 4 metres
Monday: Mrs P obvs, but I do have to go out to do the food shopping for elderly parents and deliver it. The numbers at the supermarket will obviously be beyond my control, but if it's mentally busy, I'll hold off until it quietens down. I won't get out of the car. When I deliver said shopping, I've told my parents to retreat to the living room, shut the door, and I'll dump the stuff in the hallway and bugger off.
