Have you warned your brother - what does he think?

It shouldn't really be a problem as long as he doesn't mention which flower pot the keys get left under.

My wife and daughter were walking past some fine houses on the coast, complete with tennis courts etc, marvelling at their positioning and size.

Out comes a gentleman from one house and proceeds to pop the key under the flower pot!

It must be easy come easy go.

I think that you are getting unnecessarily paranoiac.

Of course there is a risk but it is not nearly as large as forgetting to cancel the milk.

Unless your brother has contents worth £Millions, few thieves would spend the required amount of time researching such an operation. Of course, if he has a van Gough or Turner on the Sitting Room wall, it would be a different matter.
