You’re home alone; you walk out the door to get the mail. The door locks shut behind you.
How screwed are you?
[li]Not at all. It’s not possible for me to lock myself out.[/li]
[li]Not at all. I have a key hidden.[/li]
[li]Slightly. I know how to “break in” to my house.[/li]
[li]Possibly. I gave my neighbor a key; as long as they’re home, I’m fine.[/li]
[li]A little. I’ll have to call my wife/kids/a relative/a friend who has a key.[/li]
[li]I’m fairly screwed. I’ll have to call a locksmith.[/li]
[li]I’m totally screwed. It’s going to be a major ordeal, e.g. I’ll have to walk a ways to a neighbor, hope they’re home, hope they’ll let me use their phone, and hope a locksmith is able to get out here.[/li]
