...well yes, sometimes it pours. Either way I am not fond of using an umbrella / bumbershoot / brolly (whatever you want to call it). I prefer my rain slicker / jacket / poncho (whatever you want to call it).
Because my rain slicker keeps me dry and doesn't poke you in the eye.
Because my rain slicker keeps me dry and doesn't need to be adjusted to let you go by.
Because my rain slicker repels the rain and doesn't require a hallway drain.
Because umbrellas in abundance hog the sidewalk/crosswalk and are a nuisance.
Obviously this is not a practice I've adapted, this is one area of life I will award the NW a point.
