If you have the privilege of having a child ever be in your home, then chances are high you learned REAL FAST what items you *should have* hidden. Seemingly harmless, boring items, that "surely no kid will find that interesting...." but alas, everything is interesting when you're under the age of 6. So whatever it is, no matter how boring, and especially if it's sticky or permanent or non-washable.... lock it up! Probably in a fireproof save with a passcode that is not "0000."
