I would have a real dilemma with this kind of Schroedinger’s Saturday Night.
Stay In: Can wear pyjamas, booze is already paid for, almost total control of music and images, no taxi home, only people I need to talk to are people I like, total concern I’m missing the greatest night that has ever happened ever for any number of unique reasons.
Go Out: Wear real clothes, buy drinks, someone else chooses the music, full of strangers who might be lovely but can’t be arsed, probably not the best night ever and I’ve missed MOTD.
