So if you come home from church and throw your purse into the house onto the stairs and then go back outside so you can water your tomatoes and see your neighbor outside and go to talk to her about the irises you are going to give to her and then your husband, who did not go to church, leaves the house with his friend Tom to go to Summerfest, steps over the purse, which is ON THE STAIRS, which is not its usual place, and Tom, who realizes that a purse does not live ON THE STAIRS, asks, "Is Class Factotum home? Does she have a key?" and then they get into the car, your husband backs out, sees you, and yells out the car window, "Do you have a key?" and you answer, "Yes," because of course you have a key IN YOUR PURSE, which of you is at fault when you turn out to be locked out of the house?
NOT YOUR PURSE'S NORMAL RESIDENCE.
