A funny (true) story:
When I was in high school, my sisters and mom volunteered at Concerts in Garden with the Fort Worth Symphony. We did it so we could see free concerts! It was pretty awesome. Anyway, these concerts are outdoors, so there are no bathrooms, just port-a-potties. There was one concert that we went to without fail: the super hero-themed concert with fireworks. It was always really good, but there were always lots of kids there! After my duties during intermission, I ran to the bathroom before the concert continued. I finished what I needed to do in the port-a-potty and went to open the door, but it wouldn't budge!! I pounded on the door and shoved it really hard thinking that it was just stuck, but the movement caused the port-a-potty to rock! For a moment I thought it was going to tip!! I panicked. Then I started pounding on the door yelling for help. A security guy opened to door with a scowl on his face. He told me that he found some boys putting sticks through the deadlock slots in the doors locking people in. He was going around taking the sticks out and chasing the boys away. I was really shaken and rushed back to my family. When I got back they asked me what took me so long, and when I started telling my scary story, I discovered that it was actually quite funny and ended up laughing hysterically with everyone else!
