And I don't even care to shake these zipper blues

I fear I am losing my mind. For the past week or so, more than a few times I have walked in to the bathroom and realized that my pants were already unzipped but still buttoned. I cannot figure out if I am doing that in the hallway prior to entering the bathroom, or like, an hour before because I keep starting to walk to the bathroom, but then I think of something else I have to do that makes me veer off my original course. I would hope that someone would tell me if I were wandering about with my pants unzipped. I'm choosing to believe that I am doing it moments before entering the bathroom, whilst thinking of something else, and that is why I am not noting that I am doing it. Yes, that must be it.
