The Pink Friday Swimmers

Peeping out at the cold through the wooly gaps of winter layers, I arrived at the beach to meet a friend for a blustery walk. A few surfers in thick head-to-toe wetsuits bobbed about in the water, but otherwise the beach was empty save for this small group of men and women dressed in nothing but bright pink swimwear.  I shivered in unsolicited empathy; they smiled and laughed in excited anticipation.  What the hell were these people doing dressed as if it were a balmy summer's morning?  I hate the cold!
