I have just finished chemo and have a baldy head, my niehgbours chose the end of my path to have a long catch up, I gave it a while and then I went out to the end of my drive and said in manner most polite to my neighbours who were chatting at length (think ten or fifteen minutes, not fleeting) I am a vulnerable person health wise, can you please move your chat to your own side of the road.
My neighbour said you are alright we won't be much longer....
I whipped off my wig and said you need to move now, and move he did , fairly rapidly considering his age.
