It’s been a hard day. A long, hard day.
I was finding it hard to concentrate at work and, as my mind kept wandering, I kept making rather stupid mistakes, which my boss was all too keen to remark upon.
To begin with I was able to laugh it off, and come out with a light hearted excuses to keep her off my back, but as the day wore on, I actually started to run out of excuses. In the end I gave up trying to explain the mistakes away.
What I need is a ration book of excuses. Every time I mess up, I could rip one out, scan it, and send her the PDF.
