20-20 vision! Said the 90-year-old blind optician.

This is a true story. I'm used to being the exception to the rule in my family, who have all worn glasses from a young age, but when the blurry things began to get closer and closer, and the on-screen TV menus started spreading out in all sorts of unreadable directions, I thought it might be time to get my eyes tested.
It must have been this guy's own optician practice. Who the hell would give him a job anywhere else? He was literally 90, could hardly walk, was shuffling around bent over and had really thick glasses. Nothing against the guy, but was he really qualified to give me an eye test?
Oh well, 20-20 it is! Just as I was getting used to the idea of some cool glasses.
