Just like America declaring independence, it was time for me to emancipate myself from my parents (or was it the other way around?) We waved them off from George Bush airport and I've just heard that - after some minor kerfuffles with National Express coaches - they've made it home.
The last few days of their stay involved a packed schedule of dashing from one air-conditioned place to another as temperatures soared to 100F+. Dad was able to flash his Royal Navy credentials and board the local warship, USS Texas, and Pete took his Grandparents around his favourite museums.
And now, just like America, I realise that independence from kind and loving parents isn't what it's cracked up to be. Mum, Dad, Britain - come back and re-embrace your errant child soon!
