Haha, locking yourself in, is a real thing, I did it. Good thing my son was within shouting distance. I use the typical hasp, that folds over a metal stud, that has a hole in it, that I put a pin with a locking ring through. The stud twists, and because of that, there's an indent at the studs base.
I pulled the pin out, opened the door, and went in, I didn't pull the hasp back, I just pulled the pin and opened the door. When the door closed behind me, it didn't align exactly right, and the hasp caught in the indent at the bottom of the stud, locking me in.
I'm very careful now, to actually swing the hasp way back, so when the door closes, the hasp is no longer over the stud at all, like it used to be, until the day it snagged on the bottom of the stud.
With the hasp all the way back, there's no way to accidentally lock myself in.
