Some people are horrible. I'm at a recording school now taking a diploma, and they bring in a grand piano for half of each semester (for recording... haha)...
Anyways, the way some people try closing that thing!!!! They grab the part of the lid on hinges (that closes over the front once you've brought lid down), and expect they can just muscle it down... no... it swings around, and the lid comes crashing down.
A girl at university crushed her pinky finger (she was a VERY small girl), after she had snuck into one of the halls after hours to practice without permission (we aren't allowed for two reasons: damaging equipment, personal injury), so she tries to bring down the lid on a full grand, and obviously it collapses on her hand... so ya, she had a purple pinky for 2 weeks, and this was near recital time...
