When we were younger and were going on holiday dad would always enjoy playing tricks on us. His favourite would be when we arrived at the airport and hand us each of our passports to look after. He would make us check we had the right one and on a few occasions he had brought the old expired passports instead. We would all sit there panicking while he was playing along and saying we’d have to drive back and miss the flight, until he pulled out the correct ones whilst laughing at us for falling for his prank once again.
