I have mischief fairies in my garage. I go into the garage to remove a tool, only to find it is missing. I go and buy a replacement to undertake the repair, only to find the original missing tool sitting on the step in the garage. Many months later, I need the same tool again. Remember I now have two of these tools, both of which are missing. I buy another, only to find both of the original tools sitting near each other on the garage floor. I give up.
