So finally I got a working locker. Here's what happened:

So throughout the year so far, the combination I was given didn't work on the locker I was assigned. So today, I went to the Main Office to sort this out. I first had to run up * and check the serial number on the lock. They said the actual lock on that locker had a different combination, and belonged to another student. She gave me the combination and told me to check if there was stuff. I ran up to the sixth floor from the second and checked it out. * Sure enough, there was stuff there.

Back to the office! She gave me a list of possibly available lockers and told me to find one in the area without a lock. I went back upstairs * and picked one out. Went down, and she gave me a new lock and changed the database so I had that locker. I went * and installed the lock, happily put my stuff in, etc.

Then I realized I left my art project in the main office so I went back down. Got the project, then back to the sixth floor * to chill near the door to my next class until the bell.

* - indicates where I had to run up from the second to the sixth floor. That's a lot. =P
