Why the long face?

Went for an 'MOT' at my new doctor's surgery, and raised my blood pressure by battling for a parking space for 15 minutes. Doc told me my blood pressure was high. I realised why this was and got even more narked just thinking about it.

Came outside, and my mood was lightened by spotting this fine looking fellow waiting for his own parking space to materialise....it's enough to give the most resolute amongst us a long face.
