I’ve done this myself, not all the time but occasionally i will do so. My reasoning for it varies, sometimes its just boredom but other times its because i get a bad vibe of the area so i run some quick John Wick scenarios in my head in case i need to get out or defend myself (though usually i do it because of boredom).
That said i tend to be pretty cautious when out and about because i grew up in Venezuela, and i also practiced martial arts so i have a habit of keeping my guard up.
