they haven't broken ANY lockdown rules?

When we were only allowed 1 hours exercise we regularly walked for 2 but as we never got within a 100 yards of anyone else we didn't consider we were doing anything wrong.

After we were allowed 6 in a garden my mate invited 2 couples for his birthday. Few hours later another couple arrived who had previously said no. Had we offered to leave it would have embarrassed us, the hosts and the interlopers who are good friends. So we stayed.

I consider we broke the letter of the law but not the spirit.
