Once I got locked out of my house during my high-school days. My parents and siblings weren’t home, so I was essentially trapped out; it was -6 (degrees Celsius). I wasn’t bothered to go to a friend’s house and was really tired, so I decided to wait it out… but I fell asleep on the welcome mat. I was woken up several hours later by my parents (who were very angry). I had frost in my hair, and had apparently survived an entire night without frostbite or hypothermia. I’m lucky to be alive!
