Ye Olde Denim Jacket

My wife has an old, old denim jacket. She seldom wears it anymore: as far as I can tell, only a few days during summertime, when it is warm enough to only need a very light jacket. Of course, only on a dry day, otherwise the jacket is pretty pointless. Anyway, when we got it out again, we discussed about its age. My wife can't remember when she bought it exactly, but she reckon it's not much older than a decade. I, on the other hand, think it dates back from when we started dating, so must be more than twenty years old, at the very least. I remember she was wearing a denim jacket during our first dates and I have a very good memory (I'm not joking, I really have a good memory). Anyway, now I will have to take a look at old pictures to see which one of us is most likely to be correct. Moral of the story: memory is treacherous, but also serious business.
