It's happened many of times now.
Once when I was sat on a cold brick wall outside a mediocre pub linking arms with one of 8 of my best friends about 2am, slightly tipsy and very excited for a Domino's feast that would accommodate us on our sleepover with only two rooms and blankets for shelter.
We were having a chat with two (intoxicated but really lovely) local lads and an aphorism they surged in our direction has stayed with me ever since. I can't remember the exact words they spoke but it was something along the lines of "I can see you're all really close, I get that vibe. As long as you've got each other, as long as you look after each other, that's all you need." It was a passive drunken comment but it really struck a cord and has been a motto I've held on to ever since.
