Multiple sunglasses are needed

It was a particularly hot and bright day. A big sun spot has caused a huge coronal mass ejection and everything in the city was going crazy… If you were lucky enough that your cell phone didn't explode, there were many chances that a private message you had the inspiration to send on Facebook would go public on Twitter… Crazy staff like that happened all the time but Irene was used to it… All she cared about that morning was how fast she could reach the coffee shop. She looked out the window and saw all she needed to know… The big red alert sign said: "Multiple sunglasses are needed".
