What is a sunk cost? In financial terms, it's a lost cause -- you're paying for something that has lost its value to you. Let's say I spent $200 on one of those beautiful, 6-foot-high, glass-blown water bongs and named it Barack Obonga. And let's say I smoked a little too much of the special hydro weed they give to cancer patients, decided someone was watching me through my front window, ran outside in my underwear with a baseball bat, and eventually spent the next two hours sitting in a tree waiting for the imaginary guy to come back before my neighbors called the police. And let's say the whole experience made me say, "You know what? I need to quit smoking pot, it's making me a little crazy." Maybe I'd try to sell the bong on Craigslist to no avail, and none of my friends would take it because there's nothing grosser than owning someone else's bong. At that specific point, Barack Obonga would become a sunk cost; that money is out the window. It's gone. I need to accept this fact and move on.
