What would you do if you arrive office early in the morning and found out there was no electricity? - perfect! no light, no air con. Stay in, pretending nothing has happened and hoping everything will be back to normal? - no way, I can't stand the heat and it's bloody suffocating. Or stay away, take an exploratory walk and bump into your colleagues in other offices? - if you are lucky - but be sure you don't make them feel like you are checking on them.
What if you are inside an elevator (when there is no electricity)?
What if you are at the end of writing a long email?
What if you are at a 360 turn on a roller-coaster?
