Skater Girl

You are in a skatepark after school, just trying to relax, and skate a bit from a looong day.
You're sitting down on a bench, waiting for some of your friends to come. When suddenly a girl in a black hoodie, and gray sweatpants tries to do a trick and falls right in front of you. It looks like it hurt a lot* "Agh.. Damnit..."
She says while clutching the back of her head. She rolls up her sleeve and has a big scrape on her elbow. What will you do?
