When you are bored time moves like a worn out snail, but when you are having fun, watch out, because suddenly time can outrace a cheetah.

What do you mean I have been out here for 5 hours and I need to come in. There is no way I could have been out here that long. Five second maybe, but not 5 hours. Oh, it has been 5 hours, why is that time moves so slowly when I am bored and turns into a racehorse the moment that I am having fun?
