Unconscious

The gash in my elbow was still oozing yellow puss when I woke up the day after the bike collision. All I did was run into a parked car. I must have been going fast enough though, because there was enough force to open a gash in my skin the size of a quarter.
Even though I was banged up a bit, I went to school the day after I wrecked my bike. The only noticeable owie was the open wound on my elbow, so I would be fine at school. The only problem with the wound is that it made me queasy. It didn't hurt; I just couldn't stand the sight of it. At recess I took one peak at it and I started getting light headed. It was almost time to go inside so I walked in a few minutes before everyone else.
Once everyone else came in Mrs. Harvey (my teacher) started explaining the next subject of the day. I got about the first sentence of what she was saying until..."whack!” I blacked out just long enough to topple out of my chair and bang my head against the teacher's desk. The hit to the head rendered me totally unconscious.
I woke up in Mrs. Harvey’s arms and she was running! She ran to the nurse’s office and was very relieved to find my eyes open when we finally got there.
