<human>: This was actually yesterday. I'm doing a project with my science olympiad team with my high school, and we needed to sand down a wooden cylinder. I'm usually very adept at using power tools, I've been taking classes and doing after school activities for 3 years around them, so I figured I could figure out how to use a lathe (it rotates a piece of wood around and around). However, I didn't realize the piece of wood required TWO things on the ends, not one. I only put the sharp end on one side, and pushed the clamp over, tightening the piece of wood. I turned it on, and BAM!!! Everything turned black. The girl next to me screamed, and I couldn't feel my face (I wasn't the weeknd either). I went to the hospital and I had to get 4 stitches, I busted my lip. To make things worse, when they were sewing it up, I don't think they used enough numbing stuff because I felt every single thing. Lesson learned: don't mess with machinery you don't know how to use, no matter how safe it looks.

Can you give me a shortened version of the text?
<bot>: I didn't know how to use a machine in the woodshop and I got hit in the face with a piece of wood.
