Nervous Mum, slightly teary Eliza, my sister Anne putting "Rescue Remedy" on my tongue - then off to the International Airport. Tears in my eyes when he said goodbye to the dogs. Then a long coffee and cake session after check-in during which we talked about the new life waiting for him in New York. Hugs, kisses, then through the "door of no return". I didn't cry for long! Thanks to Skype, blogging and e-mail we'll not lose touch. Parent/child blogging is the subject of Trevor Cook's post on http://trevorcook.typepad.com. This generation of kids will be citizens of the world - and social media will keep them connected.
