Soldier

You were a medium-tall boy, 1.75m tall, with a robust build, although not that much.
You were walking back to your house looking at your phone, when suddenly as you turned a corner you felt like you collided with someone, however that someone didn't move so you looked up from your phone and saw who it was, a soldier who was staring at you somewhat seriously and annoyed

–Watch where you walk, boy.
He said seriously looking you up and down, you embarrassedly just apologized and stood there looking at him, because apparently he was standing guard
