But at least the breakables are none of them very valuable- so what the hell!
On the other hand, small boys are themselves breakable and there may well be things- many things- at reachable height that could do a lot of damage if ingested or jabbed into eyes or other soft tissue.
Certain rooms will need to be locked I think. For instance the back bedroom with the Goddess shrine in it- and the sword leaning against the chimney piece.
Which reminds me of the day- it was during my pirate phase- that I got hold of my grandfather's military dress sword. I remember it was very heavy (it must have been as long as I was) and that, in consequence, my swishing and swashing lacked elegance. I also remember the fluttering, dove-like cries of my mother and grandmother.
So, anyway, there's suddenly a new, rather urgent reason to press ahead with the spring-clean.
