For example, the "Oh Fuck" moment when you realize you impulsively blew an obscene amount of money on something that doesn't fit. When you realize you have inadvertently stuck yourself in the corner with some greasy bastard whose breath smells like tuna fish. When you realize you're outside and not wearing any clothes.
Ok so the last one usually only happens in dreams. Usually.
So basically, the feeling is one of "whatthefuckhaveIgottenmyselfintoohgodpleaseletthisbeadream." Its a common phenomenon. Documented by people in shiny white lab coats and everything. But the thing is, everything happens for a reason. That's what I believe anyway. Everything we go through, there's some higher purpose for that. For our "suffering," excuse me for sounding so Biblical. Not that there's anything wrong in that. These "Oh Fuck" moments have a purpose. They teach us lessons. They help us make better judgements in the future. And if not that, they make a great story to tell whilst drinking. Drinking milk.
So let's raise our glasses to the OF moments in life, because as someone not so smart once said, shit happens. Cheers.
