So often on MN I see scorn poured on posters who dare to put a little importance on an occasion - with the usual rhetoric 'do adults even do Valentines?' or 'You're having a birthday party? Are you 5?' or 'WE don't even remember our Wedding anniversary' or 'A wedding invite? How tiresome. Don't go'.
AIBU to think these people are anomalies in real life? Not for not marking occasions themselves, each to their own on that score, but to be of the opinion that any kind of fun or joy is strictly for children and us Adults should just take ourselves deadly seriously, trudging glumly through life until we drop dead? I genuinely don't know anyone like that in the real world; everyone we know tries hard to squeeze every small drop of fun from life.
Life is long and often hard enough without denying yourself (and more bizarrely, others!) any silliness or cheer. The more the better I say.
