I locked myself out several times coming home from school by bus, only to find I had forgotten my keys. The first time the garage was open so I sat in there drinking Sprite till my parents came home. A couple of times I managed to get a spare key from a neighbor. Mostly though I had to sit outside waiting for someone to come home, until my Mum got fed up and hid a key outside for me
And one time I was coming home from somewhere, not having my keys cus my sister was home and would let me in. Unfortunately she had gone in the bath and refused to let me in until she was done.
