Personality-wise, I'm more similar to my dad than my mom (while my brother and sister are much more similar to my mother in personality). Ideologically, I'm dramatically further left from center than they are, although they are a bit left of center themselves.
Financially, there's been some interdependence these last couple of years (rather than one-way dependence) since I'm still living at home (because the rent's cheap and I have a couple big monthly payments that severely limit what I can afford to rent in my area) but I help them out with things financially sometimes. I do a fair bit of housework and many errands (though I could always stand to do more). They borrow my car quite a bit more than I borrow either of theirs (mine is much newer and is better on gas than either of theirs, and I rarely have any hauling needs that would require that I use either of their vehicles).
