Does it matter if everyone is 2m apart and outside? We went for a dog walk the other day. Half-way along the road (we live in a small village) we encountered a lady with a dog on the other side of the road. We all stopped (5m apart) for a quick chat. A minute later we met her husband who was in their garden other side of a thick hedge. Another quick stop and chat and then his wife and dog reappeared. As it happened, another local couple and their dog (friends to all of us) arrived, so for a few minutes we all chatted together - very well spaced out and ALL vaccinated. Lo and behold! another friend, single lady, passed by with a container full of steak & kidney pies which she was taking to a recently widowed chap. (She is noted as a remarkable baker). So in total there were 7 people (and 3 dogs) all passing a few pleasant minutes chatting in the open air and at least 3 yds. apart. SO, just tell me what is so wrong with that? Apart from it currently being illegal that is?
As long as the 16 people were staying a couple of metres apart (not counting households) there is nothing wrong with that i.m.o..
