Mr Heathbank I was at last able to appear as more than an old photo for Catriona on Skype.
When I was small I was obsessed with the notion of travelling in Space - and the capital S is intentional. And I'm talking pretty small here - seven or so, if memory serves. But later came the kind of communications they had in the first series of Star Trek: I dreamed of face-to-face chats at the touch of a button. And here it is. Allowing for the slight time-lag when we waved to each other - as you can see, I'm doing just that - it was pretty impressive.
By the end of the call Catriona seemed to have become used to the idea that her grandparents were in the laptop. I can remember when I was convinced an entire symphony orchestra - complete with white ties and tails - fitted inside my parents' black bakelite radio. Some things don't change - they simply become more fun.
