I have had this almost biblical urge to take a dump since ~4:00 PM, but don't want to leave for fear of the fact that I might not get a chance to come back for a while. I've been prairie-dogging like a mofo for the past 3.5 hours, and have even considered going to the bathroom here (ew). Thank god I'll be home in...90 minutes?! DAMMIT!
Edit: Oh yeah, I've just now realized that holding it in too long makes my left eye quiver. I wonder where that point is where you've learned too much about yourself.
