that's actually rather cute. and to think they are civil enough not to poop in the station. we humans should be ashamed of ourselves for littering everywhere.
I used to work in a company that wobbles from the aftershocks of nearby tremors - this would've been a great back then since all the office workers ran down 14 storeys without stopping!
Kinda happens to me while I'm at work. It's like being submerged for 8-9 hours, then at the end of the day, you just miraculously 'live' again. Totally understand wolf-spiders here.
