Staten Island teacher Adriana Lopez was recently diagnosed with breast cancer. The school's amazing chorus gave her a special end of the year song.

How far into this did you make it before crying? I got about 30 seconds in. I recovered towards the end, then broke down when Mrs. Lopez started crying as she said she had great friends.

Also, this chorus is actually good! Usually, I'm very skeptical of children being used to manipulate me in viral stuff, but the chorus at PS 22 has been blowing the lid off YouTube since they started posting their videos. They even have lots of interactions with surprise celebrity guests. What I'm saying is, they did this for their teacher, not fame. I mean, they can get Carrie Underwood to stop by anytime.
