I suppose it's good that I really had to think about it. We've been married for over 27 years and I would think there would be some things that really stick out.
The first thing I thought of was my wife's memory. It's awful. I am constantly reminding her of things. Of course after thinking about that, it's not always such a bad thing. I get away with plenty due to that memory of hers. And she just rolls with it. She knows how bad her memory is so it has become more of a standing joke.
But what I think really makes me scratch my head is her tendency for OCD - but only for short periods of time and it changes at the drop of a hat. It may be Chris Cornell for example and she goes out and buys everything the guy did and that is all she will listen to. Then it was Eddy Vedder. Thankfully, several years ago her Terrance Trent Darby stage was very short lived for obvious reasons.
Last year I bought her an I-pad for Christmas. I had no idea how many temporary obsessive compulsive things you can do on one device. Thank you Apple.
