Once Upon A Time, Polaroid made a nice simple elegant model of sunglasses. I had two sets of these over the years; of course they broke and no matching replacement was to be found. Grief struck Yours Truly.
I do occasionally browse Crazy Clark's and similar junk shops, and one day about four years ago they had a near-copy of said model sunnies for the unbearable price of $1. All hail the junk shop! Didn't I look great? bruahaha snif
But even such pricey high-quality gear has a definite best-before date, and so the sunnies went south a few months ago (metal fatigue near the hinge). Naturally this happened just before the trip to AT and I was stuck with my flying sunnies (which one of my sisters said remind her of "Puck die Stubenfliege"). I didn't find any nice sunnies in Austria. Maybe it's the weather or the people scowling from birth that render sunnies unnecessary, I don't know.
Back here I embarked on another quest for gear (my brain wasn't good for anything useful after the long flights anyway) - and found another reasonable model in Yet Another junk shop (The Reject Shop, IIRC). I was content, and the sunnies cost a reasonable $6. True to the shop's name the sunnies developed a crack through one glass after 15 minutes of wearing. Of course the shop had exactly one single set of this model so it was back to square one.
But finally some (likely) Chinese knock-off artists came to the rescue: in a "Cheap Designer Sunnies" shop (oh the irony!) I found a near-perfect "Armani" model among the tons of gargoyle-style stuff. $30 is a bit much but they fit, look like I want it and I'm happy. End of Story.
