What day was my date again?

What I am writing I consider to be one of my most embarrassing moments ever. This occurred back in February I believe. One of the few times in my life I have had a second date happened to be that night, or "a" night really. Maybe I was just so in shock that I got a second date that my mind was not in the right place. Anyway, as the story goes, I get myself ready, and well that really goes without saying as I prefer to look as presentable as I can when I go on a date. I show up at this girl's door, and after a bit she finally opens the door. All was not well. I noticed that she was not dressed for going on a date, rather the attire she was wearing was definitely more suited for sleeping. "Why are you wearing pajamas?" I said to myself. "What are you doing here?" she said to me audibly. Naturally I responded that I was here for the date, as I had assumed we would be going out that night. Well she then proceeded to tell me that the date was not until the following night. At that moment, every single idiot alarm in my body went off, my face probably turned red. She graciously readied herself and we went out anyway. End of story: we went on one more date after that, then an abrupt end. And I wonder why I am still single.
