Casa de SaaM is not a tactical house, and it is one thing that I never considered when I bought it. It's basically the letter L with the girl's bedrooms at one end and ours on the other. The only entrances are at the crook of the L, so if there's a break in, it's most likely going to happen between my daughters and I.
Using rule #4, I know what lies beyond which parts of the walls. I've determined safe areas that won't cover where my daughters are most likely to be in case of needing to fire a weapon. However, and this is something I've thought about but until today haven't really put enough effort into, there are quite a few blind spots through the path from my bedroom into the rest of the house.

Looks like I'll be buying some mirrors soon.
