A few weeks ago I was driving when the sun decided to come out so I had to rummage around in my purse with one hand to find my sunglasses. The reason I could only use one hand is because of course I was
texting driving with the other, but I did manage to extract the sunglasses from the case and put them on.
This is what I eventually discovered I was wearing:

You would be surprised how long it took me to figure this out.
So the first time this happens, I pull over to the side of the road (just like I always do when texting!) and pop the lens back in. But wait, now the lens is covered in fingerprints and oh by the way so is the other one, where is that special Only Use This On Your Glasses! cleaning cloth or will the silk top I am wearing today work instead? I love being late to meetings.
I've had these particular Ray-Ban sunglasses a long time and I like them, but they have caused me to learn something about myself. And that is that I am not really a patient person.
And also that I find having to ASSEMBLE MY SUNGLASSES before wearing them to be a freaking pain in the ass.
I think you will agree that if a lens pops out maybe once or twice? No worries. But now every time I take these Ray-Bans out of the case, this is what I have to deal with.
So yeah. I went out and bought some new sunglasses yesterday.
