Dear Boss I'm sorry I was late for work today. I was in bed with your wife. Kind regards James

Dear Mr. Boss, I love this job so much that I dreamed I was already here at my desk still in the dusk. As the alarm-clock rung in my dream the phone was ringing, I kept on answering and closing deals over the phone. I already did so much stuff this morning. I believe I am worth a rise in pay.

I forgot to work for you.

i am ill

I had a flat battery and the Car Roadside Assist crew were late.
