I am sure she won't mind my posting it here:
Sir, Maybe Kate Ross should adopt a “shoes off” policy in her house (“Cat litter is tricky”, letter, Jan 5). Politely asking guests to remove their footwear is not an unreasonable request. Most of our visitors remove their shoes out of courtesy, without being asked, especially when they see the pile of shoes by the front door.
I know that I have said we are not a movement, but we do seem to be acting increasingly like one.
Thanks go to Richyrich for pointing this one out.
