I know , I know .
But ....... my vaccinations only cover me in certain areas ! Plus , it's the Postman in me .
You wouldn't want me going through the wrong door , would you ?
Oh, err, Mrs!
So you will attend. Knock on the front door with a sponge - then leave a card and go.
I found my postman collapsed, unconscious, on the road last week so I left a card on his chest 'SORRY YOU WAS OUT'.
