Can someone correct this please :)

When I was little, in the evenings I used to go to my grandmother's house. and I took the opportunity to do all the things my mother would not let me do, like playing video games in on the game boy, eating chocolate ice cream at as a snack... During one of these afternoon s, I was playing with my cousin who was three years older than me. I locked myself in a closet bathroom to give a scare to my grandmother. The problem is that after, I did not know how to get out so I was stuck there and locked out in for half an hour, waiting for my cousin or my grandmother will to remember me.

I feel sorry that you got lock out for that long! Hopefully they didn't take too long to find you!
