Do you hang out or just sit in your garage? If so, why?

There is a very nice subdivision across the street from me and I have noticed that a lot of the people that live in those very nice, expensive houses sit in their garages most of the day. They have nice decks, nice front porches, but they just open the garage door and sit in their lawn chairs in the garage. One guy actually has a couch he sits on. I’m just very curious as to why anyone does this.
