I suspect it’s known as ‘growing up’
I’ve forgotten almost everything from when I was a kid – when, how and why did this happen? I must not have been paying enough attention or something, because I can only remember about a day’s worth of stuff from the first sixteen years of my life. And what made me realise this?

Shameful. Thank goodness there are internet-types to remember things like the Little Professor, track them down and re-purpose them as novelty geek-bait for me – well, for me if I’m willing to part with thirty of my hard-earned pounds. Which I’m not.
But still, it’s one less black spot in my mind. Ah, nostalgia.
