I find (with close family) even if they annoy me so much and I don't want to speak to them, I'm willing to forgive them. If, however, my relationship with a friend was broken, I'd be more likely to just get some new friends rather than eventually come back to them. Family can't be replaced, and my parents dedicated years of their life to raise me, an argument or even temporary hatred can't change that and therefore i'm able to forgive them after a time (although I wouldn't if it were serious enough eg abuse)
Fair point
Personally, I don't treat family with any special reverence or whatever. I wouldn't forgive a friend if they suddenly disappeared for several years because they got bored of me; why should I forgive a parent for the same thing? I do understand that my situation is very different to most here -- I was honestly neglected a lot, so the argument that I owe them due to years put into me is rendered moot in my case.
I'm not the kind to cut ties with someone -- family or otherwise -- for minor grievances, however. I don't believe relationships are always smooth sailing. However, for major things, I will definitely hold them to the same standard, and don't hesitate to cut them out because just they're related. I didn't choose to be their family, but they definitely chose to be poor examples of good people.
I did, however, choose all my friends, so I suppose I'd consider them inherently
more valuable to me. That said, it's not like I have anything
against my family; anyone who has talked to me for a few conversations would know I probably talk about my siblings way too much. I look after them a lot, and I do consider them very valuable to me -- both as family, and as people.
