Your relationship with your home is one that will hopefully last a long time, so it pays to learn its most intimate details. And not to be weird, but we really do mean intimate: what turns it on (or off), what makes it hot (or cold), and its delicate inner workings.
Because, after all, your home takes care of you—it keeps you warm, safe, well-fed—so it has every right to act a little high-maintenance and demand some TLC in return. Neglect your house, and there could be hell to pay later in the form of floods, electrical outages, and worse.
So as a sort of how-deep-is-your-love kind of test, ask yourself if you know these five things about your home—and if not, maybe you should go find out.
