Every morning as I lie in bed, waiting until THE LAST POSSIBLE MINUTE to get up and get ready for work, mentally eliminating all unnecessary steps from my morning routine to give me a few more horizontal minutes, I think up excuses that I could use if I called in sick. Today's was:
The dust mites in my mattress have been especially active since the warm weather returned and they've just made my allergies terrible. I feel too unwell to come in.
Of course, this excuse has a limited time window as I'm finally getting new pillows and an allergy-proof comforter and mattress cover. They don't need to know that, however.
