The feeling of accomplishment you feel when you work out what that stuff growing in the kitchen sink is... is not really accomplishment at all.
You know that feeling you get when you wake up in a strange bedroom and there's a figure at the end of the bed and you're like, "MY WORD!" but perhaps in stronger language and then you turn on the light and it's just a shirt hanging up or something of that ilk?
Today that happened to me, except in the exact opposite manner.
I woke up in a strange bedroom and there was a figure at the end of the bed and I said to myself, "That's a shirt or something."
Then I turned the light on, and it was a SKELETON.
I said, "MY WORD!"
But perhaps in slightly stronger language.
