Having threatened our (now) 27 and 29 year olds with suitcases being dumped on the lawn when we disappeared to France, they both miraculously left the nest within 3 months of one another ! That was last year, one of them flew as far as Australia but came back on a fleeting visit this summer. I missed him dreadfully when he first went and have, like you, had to rely on Facebook, but that visit changed everything. He'd only been back in the house 30 minutes when I realised how peaceful and tidy it had been for 12 months - no remains of sandwich making left on the kitchen worktop, no tubes of toothpaste squeezed from halfway down, all my husbands socks still in his drawer, but sadly no feet thrust onto my lap for masssaging after a long day at work (only a mother would do that surely ??). He's back in Oz now and although it was fab to see him, it was even fabber to wave goodbye again, particularly knowing he'll be there to visit as often as we can afford get there !!!
