I genuinely don’t know if IABU here so could use some advice. My next door neighbour but one (lives alone) has tested positive for COVID. When he is walking his dog he sometimes knocks for a chat and as he’s old and possibly lonely we usually ask him to distance and chat to him at a ‘safe distance’ from the doorstep.
He knocked on the door yesterday when he was out for a walk, and stepped back 2 meters outdoors before chatting to me and DP. He noted after chatting for about 10 minutes that he has taken a COVID test as has had a bit of a sore throat. Turns out the test was positive (he found out today). I’m now driving myself mad thinking he’s probably passed it to us (but maybe he hasn’t as 2m away and outside). AIBU?
