A welcome home

In my work I visit a lot of people in their homes. Today a question occurred to me.
Why would someone with a tiled porch floor and a laminate hallway have a cloth doormat outside the house and no doormats inside? Your practically demanding wet footprints!
Mind you I was reminded of the fact that there's nothing funnier in the world than a hyperactive dog on a shiny surface.
Advice for today... Do you have a tickle in your throat? Book the best seat in the theatre and enjoy a good cough!
