I recommend keeping one’s head up to catch other people’s nuggets of intrigue, comedy or shock
There’s a reason why magazines run “overheard” columns and you find social media accounts dedicated to the same. That humans are capable of saying things so unexpected, bizarre, idiotic, hilarious or filthy is one of the great, simple joys in life.
Strip such remarks from their context and they can indeed be elevated into art. Or perhaps you know the context, but marvel at the opinion or observation. You might let your nostrils flare in mirth, or catch the eye of the speaker to signal agreement. Then there is the jaw-drop of something utterly moronic said behind you on public transport. Messaging it to a pal to share the goods. Barking with laughter when remembering it, months later.
