I think it gives the obviously correct answer, but I'm not sure how duelling obviosities advances the matter.

It has advanced the matter by revealing a conflict between our beliefs. We can then proceed to giving our reasons for our respective beliefs. I'll go first.

By jkadlubo's account, her parents are not her friends and cannot be. Some people have the good fortune of having a close, loving relationship with their parents. jkadlubo has never had that, and it does not look to me like there is any possibility of creating it. The best that can be hoped for is distance and disengagement.

She doesn't mention how her relationship with her sister stands now or stood then. Whether there is any future in that relationship I can't guess. No other family members are mentioned.
