I hate sunglass shopping! I wear sunnies all the time, but it's so hard to find anything that doesn't sit too high on my nose and let masses of light in the bottom or sit too close to my face and rub against my eyelashes (maddening sensation). Oakleys tend to be guilty on both counts. Nike and Adidas seem to consistently fit well, but it sure would be nice if they were cheaper - my current pair are in dire need of replacement and I just don't have a spare NZ$200/£80 at present.
Drink coffee and do stupid things faster with more energy.
