So this UPS guy just delivered a package, and it made me cognitate.
Usually when we have guests, like my grandma and friends that have been over many times, they come in the sliding glass doors in the middle of the house. However, when someone who doesn't usually go to our house comes, they often will try to go up the steps to the front porch and use that door.
The delivery guys, fedex and UPS are usually about half and half about going in the front door and going in the side doors.
If you were going to the house of a stranger, say you were selling girl scout cookies, and they had two doors, an ornate front porch door out closest to the street, and a plainer door that was set back, but obviously more accessible to the house as a whole, which would you knock or ring at?
