Celsius or Fahrenheit? Those are very different temperatures and depending where you are 19 celsius could feel super cold.

truck? 19°? happy that it's sunny? you sound like you're from CNY. all joking aside, I'm sorry you're having a shitty day, op.

If it's that cold, you likely have something you can cover your face with to be able to go into the gas station, buy a mask and use the phone to call your job to let them know you'll be late and call a lock smith. You can probably wait in the convenience store where it's warm. Once you get into your car, go to the air pump that's at the gas station and put air in the tire if you're able to. You may be able to fill it up enough to either get to work, to a mechanic, or back home. If you're not able to get to work in the truck, take an Uber. 🤷🏽‍♀️

2 Days ago my car wouldn't start because the battery froze and I walked to work only to find out had I had the foresight, I could have asked a coworker to pick me up. It was -19 @ the time and that night went down to -39. The 19° totally brought up memories since mine was -19. Can't wait to move back home...

sounds like we have similar luck

The good news? You didn't wreck it. IF it's his pride and joy, I think he'd be furious if that had been the case. A flat tire is easy to fix. As for locking the keys in the car? Hopefully using a slim jim or a locksmith won't leave any permanent damage.
