The longest I've ever done involved me returning to university to see some old friends. I got the Megabus from London to Sheffield early in the morning, arriving around midday. My friend text me pretty much the moment I got off the coach:
"Hey man, where the hell are you, the beer festival has started"
So I went drinking with some old coursemates (now PhD students) for six hours, pretty much pre-drinking for a night out with my best friend, a girl that is the biggest fucking hippy you'll ever meet.
I left my coursemates and went and joined her. The event I went to with her was amazing, as it always was; taking place in a warehouse till 6am, nothing I couldn't handle. Afterwards, outside, she told me:
"Ok if we go to this after party?"
Yeah fuck it, why not. It's her birthday weekend and it was a bank-holiday on the Monday. The after-party would fizzle out about 8am, so I thought.
Eight fucking hours later the after-party began to resemble something out of Dante's Inferno, my best friend being Satan: she showed no sign of letting up. I rang one of my friends that went to the beer-festival the day before and was like:
"I need to meet you. Can we go back to the beer festival, or the pub, or anywhere. Please. I need to get out of this fucking house".
So I managed to escape, just. My best friend text me about 6pm to let me know she'd pick me up in the taxi. We got take-away and FINALLY went to bed.
Girl is fucking nuts, but I never get a better night out anywhere else.
