Which Walk do you Walk?

I think the way people walk can be funny. What really brought this to my mind is because one of my friends told me she has to consciously move her arms when she walks. Then I started to think of how awkward she would look if she didn't move her arms. Then I started watching people. People run to class, backpack bouncing, legs moving speedily underneath. Or they slowly meander, headphones in, looking at the phone in their hands as they text. Some walk quickly and with a purpose, others walk slowly and leisurely and chit chat with their friends. I found it interesting to think about the different types of walks you can have.
