all grown up?

After some discussions, thoughts, number crunching, but (surprisingly) no arguments, we came to an agreement to buy out my father, since he is moving out by June anyway. We are refinancing. Its exciting, a relief that we are not getting screwed (again...hmm). But it's a bit scary too, I mean sole owner of 'my' very own house...
Gulp, does this mean I am all grown up now?
