You are a member of the Batfam.

Unlike the others though, your father, Bruce Wayne won't let you fight crime with them. You don't know why, but ever since you were a kid any attempt to do anything close to what your family does has been blocked by your father.

Which is why, when the Bat-Signal goes off on family game night, you stay behind to put up the peices while your family runs off to do their jobs..
