weekend worrier
A person who engages in their chosen hobby only at the weekends, but, instead of enjoying themselves, spends the entire time preoccupied with troubling thoughts of a mostly mundane nature, e.g. office politics, family strife, the spectre of their own mortality.
'Yeah, I guess you could call me a 'weekend worrier'. Note how I pronounced 'worrier' /wʌri:ə/, not /wɒri:ə/', which is probably what you expected me to say... It's a play on words I sometimes do to amuse people, but usually just myself... Well, I like it... Aaanyway, great party, hey? Fleeting distraction from the universal certainty that we'll all be dead one day... Yep, nice talking to you, too.'
