I have to fangirl you for putting it in words in such a perfect manner! :))

A walk can be highly beneficial, be it characters or writers. *nods* My family often gape at me when I suddenly jump up. "Anyone wanna go for a walk?" "Erm, no, mother, it's raining/sunny/cold/hot." Walks are therapeutical. And they always happen for good reason. A need for a walk is kind of like the need to play the piano, you know?
