I noticed another sign today, in the elevator. It's above the emergency phone, and it contains instructions on what to do if the elevator breaks, but the perfect part of it is the first line, which reads, in all caps:
TRY NOT TO PANIC!
So supportive! So true! Try not to... even though we know you will, and we would too if we were there with you, because who wouldn't!?!... just try. And even if you do, that's OK, just move on to step two and we'll come to get ya out. Comforting!
