Illogic

With the city being drenched in rain and all the last two months, people are husting down the street with large golf umbrellas and rubbery rainslicks. But please explain to me, dear reader, why the same women of this burg who go to great lengths to cover their torsos and heads from precipitation wear goddamn flip-flops on days like these? Am I missing a Jenga piece here?

If the clean rainwater is no good for your hair and shoulders, how can the foul broth of oily runoff, dog urine, feces, and vomited-up pad thai be any better for your instep and calves?
