well i wish i had someone like your SD willing and able to fetch shopping for me.
i used to go once a week, BC; now in the AC era i go less often. trying to eat my fridge completely first, and its only small, no freezer; plus sundries, so as to make most use of trip to shop and fill it up. i regard the shopping trip with trepidation.
that's almost alliterative, the trepidation trip.
anyway, it seems to me that you are taking an unnecessary risk. you could till go out, when it's quiet, for exercise, and avoid people.
but shopping is different. it is a targetted activity. numerous people are heading for the same location, and once inside are milling about looking for items, difficult to keep distance.
also what about the risk you may present to others.
for all you know you may already have the virus and be spreading it about by unnecessary trips.
why take a risk when the stakes are so high, in the cost/benefit analysis. it just doesn't add up to me.
ps, whoever mentioned helmets and the law, i can remember the debate when they became mandatory.... just saying. we are not all spring chickens. and the point was clear enough anyway. or is this more about point-scoring rather than an honest exchange of views. seems rather childish.
stay safe. keep away from shops if you can. and people.
(but it's what I actually think).
