I was driving my girlfriend to a psychology class that she had asked me to sit in with her. Once we had gotten to the building, we walked in and found the double doors leading to the class room. One of the doors was completely shut. When we opened the other door, a flood people came out and only she was able to get in before the door completely shut.
One of the guys that left the room was holding onto an orange plastic ball. He swung it around and lost control of it, and he released it and it was rolling on the ground. Unable to get into the room, I texted my girlfriend that I'd just be out in the hallway when she got out, and I proceeded to try to get the orange ball.
The ball itself never lost momentum as it traveled through the hallway, and I followed it. After some time, another guy appeared with another orange ball and he threw it at me. I caught it and found myself with both orange balls in hand.
