WTF?

I did something the other day that I just have to post. I was getting my clothes together for work and wanted to wear my new black pants I got from Target. I looked in the area where I keep my pants and they weren't there. I looked in my wardrobe and they weren't there either. I looked in my clothes hamper and in the hamper where my clean clothes have been sitting since two weeks ago when I did laundry. They weren't in either place. I thought I wore them when it rained so I looked in another room thinking I must have taken them off to dry. They weren't there. I thought they may have been mixed in with my mothers clean clothes so I checked her clean clothes bin also. Still nothing. After 30 minutes I realized that I never bought the pants in the first place. When I was in Target, I had two pairs of black pants, but at the last minute I put one of them back. I've done a lot of stupid, crazy, off the wall stuff, but I have never looked for something I didn't own. This has never happened to me. I realized that I had missed a few days of meds but I've never done something like this. At first thought I laughed, but the more I think about it, it's kind of scary. Does my meds (or lack of meds) have that much of an effect on my memory, or do I just not pay enough attention to what I'm doing? Has this ever happened to you, or am I alone?
