And this is the reason

That I have not put a table and chairs up there, and there is a really very sound deadbolt lock with a key on the door. Which key is hidden in an entirely different room. That is, this is the view of Nel's lovely garden from my lovely garden. Please note the complete absence of any kind of barrier preventing small boys from dropping from one to the other, inadvertently or otherwise.

*shudder* It will remain a garden of my own for as long as I can manage, or at least until they are old enough to shinny down the drain pipe.
