A pub meet with friends / bandmates from a long time ago, haven't been around a table for damn near twenty years...
... and this might sound like an odd thing to smile or laugh about, but one of our number finally admitting that he was, ahem, 'knocking off' my then-girlfriend for a while...

I just laughed my arse off when he told me. To hell with her, it was one of those mind f-ing, awful relationships that my earlier and more shallow / pretentious self misunderstood as being 'love'

, I'm sure we've all had similar, she was bad news from the start and this just confirmed that I was well rid of her. Yet another bit of emotional baggage lost!
He was less happy when I told him about what me and his Mum were getting up to at about the same time ...
(that. was. a. joke.)
