One of my values, as a person, is to endeavor to never be a person who throws a stone in a glass house. In my experience, I’ve found that there are two ways to avoid being a person who throws stones in a glass house.
The first is to try, to the best of your ability, to not live in anything nearly so fragile as a glass house.
The second, and perhaps, most important way to avoid finding yourself as a glass-house-stone-thrower is to simply not throw stones. This is especially important if you are not certain, beyond a shadow of a doubt, that you are not living in a glass house. However, I find that there are benefits to not throwing stones even if you are reasonably certain that you find yourself living in a house of brick, stone, concrete, or even conventional stick framing. For one, throwing stones carries a certain risk of injury to one’s self and others. For two, there’s really no perceptible benefit to throwing stones in most cases. For three, it is simply exhausting.
There are, of course, some glass houses that simply need to be shattered from the outside by a well-thrown stone. This is yet another reason to keep your throwing arm rested and the glass out of your hair.
