I've just remembered.
This time tomorrow I'll be on an aeroplane to Barcelona, gripping the arm-rests of my seat in pure terror and vowing I'll never leave the ground again.
Until I go to Amsterdam. And then Menorca. And then Vancouver. And then Florida.
Michael Palin had the right idea in Around The World In 80 Days; boats and trains are a much better idea.
I'll be sure to send a postcard...
I also made my peace with First-born tonight; I've had to promise her a trip to the seaside, fun in a funfair and some painting of pots. And I've also had to promise to leave the mobile phone and pager in a box. Buried in the garden.
