I was sitting in less than cool airplane waiting for a group of travelers who were delayed due to issues with their bus. All in all we were only delayed for 30 minutes which is no big deal at all. That said, it was getting hotter and human nature kicked in so I was getting grumpy. I found myself getting annoyed at the late arrivals even though it was completely out of their control. Finally, I caught and checked my attitude and told myself to breath and chill.
