Disoriented

I woke up this morning thinking it's Friday and I missed my 7:30 am exam. I really hate it when that happens. First I gasp, then my heart starts pounding, then I have to think what the hell is today?! How can I turn off my alarm without hearing it?! Then, I have to think what yesterday was to figure out what today is and then I just give up and check a calendar. Whew! Thank goodness today is Thursday.
