And you'd be away from the weird situation with your sister. It sounds to me like it might be a good thing... when will you decide?
That's the thing. It's one of those decisions that timing is everything.
And, the way I mull tihngs over forever before actually doing anything, it'll probably be spring before the move is made.
Oh, and my sister would be going to, but she'd be in an entirely different department (IT). So the situation would not be so weird.
