r/AskReddit; What Seems Harmless, But Is Incredibly Dangerous? What Never Fails to Make You Tear Up or Cry?

A nurse tells about a girl who had a pin in her mouth, and then accidentally sucked it in where it got temporarily lodged in her throat, dislodged, then lodged in her bronchial, requiring major surgery. Another kid was running with a toothbrush in his mouth, ran into something, and almost punctured an artery. I also read comments that might make you tear up or cry.
