I am currently housebound with a torn ligament in my knee and a trapped nerve in my neck - the latter is because of the former, I can only get about with great difficulty on crutches and am in considerable pain (despite enough pain killers to kill a rhino) - and we don't have a downstairs loo so really it is just quite a drag.
So somebody knocks loudly on the door, I get up, shout that I am coming, it takes me about 6 minutes to hobble to the front door. When I open it there is a gormless looking woman with a clipboard who gapes at me for a couple of seconds then says
"Oh sorry I've come to the wrong house, this isn't number 4 is it"
she then walks off
Would you have been rude? Or lovely and understanding?
