Yesterday we had a fire drill but it turned out to be a false alarm.
Anyway, I work on the 23rd floor. So I had to walk down the stairs to get out of the building. At one point my legs were aching and I thought I must be near the ground floor, only to look at the sign saying I was on the 11th floor. Next thing you know I finally get to the ground floor only to see people had already started to go back upstairs.
Today my legs are still letting me know about it.
