New Shades?

When going for job interviews in the past and on generall occasions people often ask whats the most embarrasing thing thats ever happened to you? Well hands down this is THE most embarrasing thing thats ever happened to me.... About a month ago I bought a pair of sunglasses from Primark and i do believe they cost me £1!! I got a few comments here and there alongside the usual banter that I get from my housemates, asking me why I was wearing 3D glasses from the cinema! So anyway yesterday the sun was shining and I was walking from the station into work and i pulled out my £1 shades from the bottom of my bag and put them on. A pretty standard task, you would think, so i was walking and noticed people staring at me slightly paranoid but again  i was wearing my new maxi so i thought people were just looking at it. I must have walked 800 metres before i gazed into a shop window and realised i had been walking with one lense in and the other out!! I'm stil laughing i can't believe any human with a fair amount of common sense could do this! Note to self : don't buy primark sunglasses ! or better still dont be such an idiot !!
