Locked In

One time me and my family took a bus ride to an amusement park. The bus was really cool and it had a bathroom and everything. I was five at the time and I had to go to the bathroom. I went in and two minutes later the light went off and the door locked from the inside. I was trapped in there. I was very scared of the dark so I started hyperventilating and banging on the door. One or two hours later my mom opened the door and I passed out. I will never use another bathroom on a bus again.
