Whenever I'm walking / travelling / cycling alone, I get occupied in my own fantasy world and, if you're lucky enough, can even find me talking to myself. What's even better than talking to myself, sometimes I make my own sound effects. (Terribly, ofcourse.) Obviously, I press my own mute button when there are people near.
Also, in the summer when it's really hot, I enjoy going out for walks around dawn, around 4 to 5 am. Not for too long, like, half an hour or so. I just enjoy the world when it's quiet.
Then again, I don't think that's odd when you think about it. For one, everyone sleeps. That's a fucking huge bonus. Also, it's still cool rather than the sun frying my brain. Also, I get to watch sunrise while walking around aimlessly, with none around to judge me.
