I locked myself out. I forgot my keys on the dining room table where they were of absolutely no use to me! And this instance of my dreadful forgetfulness was an expensive one!
So I called a locksmith and after watching the poor man work on what was, apparently, an amazingly secure lock for nearly an hour and a half, I am £75 poorer but am happily inside my lovely and warm flat! I can now say that the stairs in the stairwell outside my flat door weren’t made with comfortable lounging in mind!
Lesson learned: Make sure your keys are where they’re always supposed to be, in your purse!
