Paranoia

I think that my experiences as the victim of theft have finally driven me to the edge of insanity. This afternoon, I was about 15 minutes' walk away from the hostel — on my way to go exploring Montjuïc — when I was suddenly seized by a flash of paranoia. "Oh s$#%", I suddenly asked myself, "did I shut my locker before I left the hostel?" I knew that this random, irrational fear was most likely unfounded: but I also realised that so bad was my paranoia becoming, that if I didn't turn around and return to the hostel straightaway (to check the locker), then I'd have no peace of mind for the rest of the afternoon. So I walked briskly back to the hostel. And, as I suspected, I had indeed remembered to shut my locker, and it was locked safe 'n' sound when I inspected it. Dear G-d: what on Earth is this trip doing to me?!
