Reasons to be cheerful (#2)

I got a phone call from the dentist's today announcing my dentist was off sick and my appointment had to be rescheduled.

Phew...I really don't like going to the dentist.

And...

I'd forgotten about the appointment, so if she hadn't been off sick I would have missed it and have had been charged for my forgetfullness.

Ah...serendipity!
