Hands Off My Lock!

I know this is petty, but I've got to share this.

I go to the YMCA three to four times a week to use the weights and for water aerobics. I put my belongings into a locker and use a combination lock to keep my stuff from getting stolen and/or plundered through.

I set it to a particular number when I leave the locker room. When I come back, it is never, I mean NEVER, where I set it when I get back. It's not just a couple of digits ... I mean it's overtly obvious someone has been messing with it. What is it about the lock that someone just has to play with it or try to figure out the combination? Geez!!

I learn more about human nature every day. :-(
