What happened? You used to be cool, hell you used to define cool, and now... Now it's like a sad $3 handjob behind a dumpster from a hobo with no teeth and all you can think is "I wonder if he'd be willing to blow me?"
Walk away, this isn't what young you dreamt of surely. Well there was that one dream involving a three-way with a pigmy goat and a former miss universe who was now in her 80s, but at least the goat was female. Ask him to remove his finger, zip up your pants and leave. Even the hobo will be thankful he didn't have to give you a rusty trombone though I'm sure he'll be sad to miss out on the extra dollar.
It's ok, it's a slump that's all. You'll come back from it, build yourself up again, rebuild your confidence, once again be the life of the party. But it takes time. These things come and go, but to sink so low, so quickly boggles the mind.
What happened? Just yesterday you were on a high of cocaine and LSD partying to music in your head while Playboy models walked around singing out of tune, but hey at least it looked nice. Now, you've spent the last 3 days running around the bush looking for a Erythroxylum australe plant even the search and rescue crews have given up. The assumption is you're dead or happy, either way no one cares.
So just walk away from the hobo put your clothes back on and write a post. I'm sure Curie will come by again.
I am nominating
