If you're a truecel like me, you probably either walk with your hands in your pockets, or just walk normally but without your arms moving one bit. At least that's what i do, and always did. Swinging my arms when i walk, feels very unnatural to me. And i wasn't even aware of the fact, that most people are moving there arms while walking, until it was mentioned to me by a fellow student when i was 12. He was making fun of the way i was walking, and said that it looked weird how my arms weren't swinging, and he even tried to "teach" me how to walk properly. Until then i was completly oblivious to it, and instead of following his advice, i just started to walk with my hands in my pockets, since this option was way more comfortable, and looks less akward, than my pathetic attempts of trying to walk like a normal person. Sad society this is isn't it?
