. For example: having a new friend from a fighting country over to your home where there are sliding glass doors and big picture windows, may prompt a response that having all that glass is not safe, their fear being that someone could come up to the house and shoot. After all, he/she may be used to living under terrorist conditions, and having to hide under furniture, and stay away from windows and glass. Yet we may sit in front of our sliding glass doors and don't even pull the drapes! You can imagine the terror this visitor would experience if he/she were to enter a newer house with much glass and/or solar panels, or a newer office building built with a lot of glass.
