How's this for genius ...
A friend of one of my clients is married to a bloke with dementia. They live in a nice house on a main road with a large backyard.
Hubby wants to go wandering out the front door, but if he does he will be dead hubby.
Not interested in the nice backyard.
Wife locks front door which makes hubby angry, feeling he is trapped.
So, knowing that her hubby is an old-school gentleman, the wife makes up a sign and sticks it to the front door.
Sign says "Ladies Only".
No more problems.
