Growing up, my half brother was over my house all the time. Sometimes he stayed at his mom's house, but other days he would be at our dad's house, my house. He would also spend a lot of time at his friends's houses and his friends would often visit my house. Now rents him, his sister, and his friend rent out his mom's house from her.
I don't know, I've never thought of that. I've always been really close with my friends and their parents are super welcoming. Once I was old enough to live on my own, I chose not to and got a place with my friends instead. Now that you've got me thinking about it, I guess it makes more sense that home is more of a feeling than a place. Home is a place where you feel comfortable and where there are people that care about you.
