I've had my faith in humanity restored, or at least that bit of humanity that stuffs things through my letterbox on occasion.
Like a complete cabbage, I left my keys in the front door this morning and only realised 8 hours later when I was about to leave work. Got home to find a note from the postie saying that words to the effect of "you're a complete cabbage, you left your keys in the door and I've dropped them off at No.70" - that's definitely a couple of bottles of the foaming ale I owe him.
Even better, I'm now on holiday until May 3rd.
