How you know when it´s home

I was just about to leave the house and as I turned to leave I saw my shoes dotted around the room. Each pair marking the place where I took them off. My dad was the first to notice this habit of mine: ´you leave your shoes EVERYWHERE!´ he would say before dumping them back in my bedroom. And that was even before I really had shoes, you know, lots of shoes. As I shut the door behind me, I stopped and smiled. Because I thought to myself: this means I must feel at home here.
