We had been ‘volunteered’ to take a Chinese man and his elderly mother on a tour of the Scottish highlands.

The ‘elderly mother’ seemed rather childish to me, stuffing herself with sweets in the front passenger seat of the car. When I peered over from the back to get a better look at her however, I saw not an old woman, but a toddler.

She was not pleased to be wrenched from the front of the car and strapped into a seat at the back.

We also ensured that she had a proper early bedtime when we returned home.
