A. I support the idea that the family is very important in our life. But I don't like the idea that friends are much less important. On the one hand, it's great to have good relationships with your family members, but on the other hand, noone can fully enjoy his or her life without friends.
B. In some ways, I agree with the idea that life isn't worth living without friends, but at the same time people should take care of their parents and siblings and be interested in their lives.
C. I abcolutely agree with the idea that real friends are really rare. I support the idea that if you have such friends, you should try not to lose them.
