The longest day

According to my calendar the longest day of the year is next week. I love this time of year. It is now nearly midnight and there is still plenty of light in the sky.
According to my diary however, today was definitely the longest day..... Ever... No less than 5 tests, plus 7½ hours of other lessons in Ullapool.
Ross, Lauren and Paul did themselves (and me) proud by all passing, with a respectable eight driver errors between the three of them. Sadly, my other two tests weren't as successful, but we'll put it right next time.
A slightly strange feeling having all those tests then, at 3.30pm, realising I still have five more lessons to go. When I finally finished, at nearly 9.30pm - 13½ hours after my day started - I was really looking forward to a pint. But the best moment of the day came when, as I parked my car, Paul pulled up alongside. In the ten hours since passing his test he had bought himself a car and taken his girlfriend out for a day out in Inverness. His expression was a combination of relief, delight and, most of all, achievement.... It made my day.
Tomorrow won't be quite as demanding: Only (another) five tests and five other lessons. But, if it is half as rewarding as today, I will be the happiest instructor in Scotland.
