Friends Reunited spawned a wave of nostalgia that coincided with the creation of our old school memorabilia web site. That resulted in a Yahoo Groups forum. That meant there was enough worldwide publicity to organise a whole school reunion in 2002 - spanning cohorts from 30 years. The school itself had disappeared in the comprehensive reorganisations of the 1970s.
The Yahoo forum in the run-up to the reunion gave some indication that personalities hadn't changed much in some 40 years. It was interesting at the reunion on the campus to see old rivalries and frictions sparking immediately. One old Head Boy apparently hadn't adjusted to the fact that he no longer held any authority over his peers.
The surviving old teachers were interesting - although there was some reservation about the one who could never keep his hands off the VIth Form boys. The teachers were at a disadvantage of being never forgotten - but themselves usually could not remember the pupils. Each year of their career they would have had at least sixty new names and faces to remember. The pupils' faces were now generally much different - although a few looked as if they must have a portrait in the attic.One cohort went off to have curry together afterwards - undoubtedly a strong bond there.
Immediately after the reunion the Yahoo group went into terminal decline. It seems as if the nostalgia was satisfied. Those who had missed the reunion occasionally ask when there will be another one. The answer is "never". The Friends Reunited wave subsided. Most of the teachers are now dead - and attrition is setting in for the pupils too.
The memorabilia web site continues with occasional updates when someone new discovers the internet and Google. They look at the pictures, add names, and possibly memories. Although occasionally someone says "I think that is my younger self - but I'm not sure". Looking at the panoramic picture of several hundred pupils - it is a wonder that there are a few individual faces as yet unnamed. Why do none of their peers remember them? Sad.
The happiest days of your life? Possibly. Simple pleasures - cruel injustices - but certainly formative experiences.
