I got home and my sister was lying at the side of the house, looking kind of out of it. I tried helping her up but her legs weren't really working... I thought it might be drugs (she's 17), and I called the cops. They got here and asked me questions about what happened because my parents were at a concert, and then took her to the hospital. My parents just got out of the concert and called. It turns out she either had a stroke or seizure, and that I saved her life. She still can't talk, but she can write. She also doesn't have as much feeling on the left side of her body now.
