Do you think you provide housing? Here's a list of common signs:
If someone stole all your tools, you'd kill them, and you don't think that's weird.
Unhealthy relationship with caffeine (bonus points for other substances too)
At least one fucked-up bone or joint
There's some Liquid Nails or silicone caulk stuck in your favorite work shirt
Your hearing isn't as good as it used to be
Regular porta-shitter use
If two or more of these fit your lifestyle, you may be a provider of housing.
