Sometimes life hands us a lemon. This is just one of those things that happens in the run of our daily lives, a truth, an undeniable fact of our existence - a thing which defines our state as mortal, fallible beings, and which clarifies one particular aspect of life - something which humans spend their lives searching for.
Control.
Either you have it, or you don't. And as human beings - we don't. We may have the illusion of it, the temporary illusion where we may have power or influence over others, or a situation - but this passes, as do all things. Eventually the wheel turns, and those on top find themselves lying in the road - asking what happened and what the number of that bus was. Ain't karma a bitch?
Once burnt, twice shy.
