What's funny is if you lock the doors, it will lock him inside your house when he get's back.
So, you can't even kick him out that way.

We did that as a joke to a friend after a wedding.

Booting someone would be pretty useful, but it would require some restrictions. Just as long as they live in the home, it should be fine to allow people to be kicked out.

Another nice feature would to lets us "knock" to enter, letting restricted homes be opened to specific people while you are there.
