Why is it...

Why is it that it can be 89 degrees outside right now with an expected high of 99 and I still need to have a little office heater on under my desk?

Why is it that when you are a little kid all you want to do is grow up and have a job and not have to go to school and take naps and then when you are an adult all you want to do is be a little kid and go to school and take naps?

I may add to this list as the day goes on. Feel free to add your own in the comments section.
