First period, normally 8:00–8:50 - Homeroom. This was the most coveted time for homeroom - plenty of time to goof off, work on homework due in other classes, flirt with boys, etc. A buffer zone between waking and having to attend class.
Since I was new to the area, that meant I didn't know anyone or my way around the school. As much as I would have loved to get to my class early enough to get a seat in the back, walking in heels and having boys trying to talk to me didn't allow that luxury. By the time I arrived, the back half of the room was already filled, and there were precious few choices in the front half either.
Oh well, no time like the present.
