I'm not sure how concerned to be.
On Wednesday evening I stopped the car to talk to a neighbour, window down and neighbour possibly 1m away from me, definitely less than 2m - just used a tape measure & 2m-seems loads more than shop markers. I didn't think there was much risk as we'd both been home & careful etc through lockdown. I'm not sure how long we spoke for - probably less than 10 mins but potentially 5-20 minutes. Neighbour didn't cough or sneeze on me.
Neighbour has tested positive today for covid & messaged to let me know. I feel fine. Tired as been to climb little local mountain today but unsure if I should isolate for 2 weeks now or am ok as long as I have no symptoms and am careful.
Also, is there anything I can leave on neighbours doorstep that might help or be useful to them? All I can think of to do is bake them a loaf of bread
