As a superpower, it's not much to brag about (but I'm going to).
My abilities are strictly limited. They only work inside my house, and only on my family. Don't come running to me if you've lost something important; in fact, my abilities don't seem to work on myself.
You know the old saying, "Home is where the heart is." (There's another old saying, "You can't go home again", so by the associative property you can't go where your heart is. QED. Thanks again for nothing, English language.)
