Our next door neighbour is a gentleman in his 80s, very nice and no existing health issues that we know of other than that he is very hard of hearing. He lives alone in a 3 bed house. I have a phone number for his son who lives a few miles away but don't know him very well.
This gentleman is really not social distancing. He is going out by car two or three times a day, the same as he usually does. He isn't having visitors like he usually does but he is definitely going out.
Yesterday, my daughter accidentally hit a tennis ball into his back garden and when I went to collect it, I edged round the edge of his front garden to give him space, saying "best be careful" and he said "oh yes, I forget". I've offered to get him shopping but he thanks me and tells me he doesn't need help.
Then today we had a delivery and he came out of his house to chat to the delivery driver the same as he always does and was definitely not 2m away - in fact he came onto our driveway. As the driver drove away, our neighbour walked back onto his driveway and had a coughing fit where he actually hawked on the pavement (yuck).
I think I'm equally worried about him and for us! Should I say anything to his son, or is it none of my business? And how worried should I be about having probably been within a metre of him getting the ball yesterday, even if only briefly?
