i feel like a dork

i was sure i had class at 2:30. so, i walk over to stuart and try to walk into the classroom and i see people that definitely wouldn't be in my class. and then i see the teacher that is definitely not my teacher. since i was a bit early, i thought i'd just wait in the hall. i see one of my classmates waiting too. finally, it's exactly the time class starts and we're still waiting so we wonder if the room got changed somehow. we decide to look at the classroom assignment list posted in the hall and lo and behold, our class starts at 3:30. and i was so sure i had written down that it started at 2:30! at least i wasn't the only one...
