To describe today is very difficult.

We've been at Mum and Rod's as we've done many times before, then suddenly it hits us. Here's Heathrow Airport. Mum's going to cry and we're off on an adventure into the unknown.

Richard's Mum and Dad had also been moist-eyed and apprehensive as we'd left Chelmsford for the foreseeable future.

Kate had to return to uni. in Leeds a few days ago with exams on her mind - plus one or two other things!

We're taking some hospital equipment to Ghana and it's quite heavy. Let's hope there's no fuss about the weight of the baggage - there isn't.

Sitting on the plane Ana's thinking, "I'm not sure this is a great idea..it's just too much, maybe a sense of excitement will enfold me soon...!"
