I came back to the UK around 15 years ago and alone, bored and lonely I guess and with social media taking off big time, I looked and found a contact.
I did nothing for a long time, heck it was just information but eventually I asked someone via a message if XYZ person was still around and as these things do, I got a message back from XYZ.
A few catch up emails, a joke or two about the intervening years, about 20 years I think, then a couple more emails and then nothing.
Too much time, different lives now, we're old (relatively) and though I haven't aged fantastically, they have aged far worse and look far older and almost pensioner status.
Yes, I'm being vain but the heart stopping, attractive, sexy person from the last century was now just about (to me) attractive but slid off a cliff soon afterwards. They might equally say the same about me !
The past is best left buried. It dies a long time ago. Let it rest in peace.
