It was a real rush at the end of the Turku conference. Poor GW did her best to get me to the airport in time for my flight to London Heathrow (and onwards to meetings in Swindon), but I got distracted by shoe shops and then lost my brown suitcase.

The dodgy taxi driver who carried his wife and children along with every fare finally agreed to take me to the terminal at 8pm for an 8.20pm take-off and – inevitably – I missed it.
