1) In my early 20s (seems so long ago now) I went for a holiday to Rhodes with a mate. At the start of the second week on the beach we were walking back from getting some refreshments when I heard my name called. After a bit of confusion, especially since I didn't have my glasses on, there was a girl who had been in the same year at school as us.
2) A few years later I was working in the NW of England but I'd got an interview for a job back home in Scotland. The interview was on a Wednesday at the end of October I think, so I'd combined the need to be in Scotland with a visit to my parents. To kill the time on the day before the interview I'd gone for a walk up a Munro (Scottish hill > 3000ft for those not in the know) to the West of Loch Lomond. About 75% of the way up I could see another walker coming down in the distance. As he got closer I began to think he looked familiar. It was a bloke I'd been in the T.A with in England and who'd left a couple of years earlier! He was the only person I met out on the hill that day too.
3) Another few years later, and now back living in Scotland as I'd got the job above, I got a letter out of the blue from another old friend I hadn't heard from for a long time. I'd moved house nearly 6mths earlier and my post re-direction was just about to run out so it was lucky shed decided to to write then and not a week or two later. She too was a friend from my days in the T.A. We'd joined at around the same time, with a few others, one of whom I was even friendlier with as he lived fairly close by. This guy I'd lost touch with when he joined the regular army.
Anyway, he'd eventually left the army and bumped into her and they were now living together. I went down for a weekend visit and was introduced to the guys sister, who was in the process of getting divorced. They got married a year or so later, and not long after that I married the guys sister. So now, about 10yrs after leaving England, and the T.A., both my brother-in-law and sister-in-law were people I'd joined up with over15yrs earlier. Unbeknown to me I'd also met my inlaws (and the wifes grandparents) years before I'd even set eyes on my wife.
I'm still happily married, with two step-kids and one non-step-kid, but unfortunately my brother and sister-in-law are currently in the process of divorcing.
