What would be good or bad about having a twin off the grid?

It would be akin to blaming smelly farts on the dog.

One could be a super hero, and the other could be someplace public, so people could not guess it was them.

They could have parties that go on for days, and nobody would know the hostess was getting naps.

One would be damaged as being the lesser or hidden twin.

The smarter one could slip into class and do the twin’s tests at school. ;-)

One couldnt be traced thus freer than any of us.

@joeschmo, my thinking about school is one could attend school monday, wednesday, friday, the other tuesday, thursday. Whomever is not at school could be homeschooling. Every other week they switch. Almost never a sick day.

That system has potential until they start disagreeing on friends, a boyfriend comes along, and differences of opinion about extra curricular activities.

Yeah.
