Lock up in my room

Was locked up in my bed room yesterday. Not by anyone else, but the lock just decided to fail on me. The ‘plunder’ cracked and broke into pieces, and stuck on the door itself. And I was locked in my room, without my phone, without internet, without water for more than an hour. Luckily, my dad was a locksmith and we stay in the same building came to my rescue. I was told it is my 2nd time locked alone in a room and my first time was when I was at a tender age of 2 or 3 years old.
