What does your walk look like?
Try to describe your walk: how long is your stride? How long are your legs? Do you step quickly, or take slower steps? How do your hips move? How do your arms move? Vigorously? Not at all?
Do you look outwards in a focused way? More absent-minded? Do you tend to look down, perhaps checking for uneven footing? Can people hear you coming or are you quiet? Do your steps sound confident and strong, or something else?
When you are with other people, do you tend to walk faster or slower than them? Is it different at different times? Going down stairs or upstairs? Hiking? Walking on pavement? How is it different and why?
How does it feel to be in your body when you walk?
That should be more than enough to think about. If you were an author, how would you describe your walk?
