There's a school of thought about behaviour traits which suggests that when one dislikes the behaviour of another, it is because these behaviours are held in oneself, and it is unpleasant to see these mirrored back - leading to antagonism by both parties. Not always the case by any means, but might be worth looking at when trying to understand others, particularly when difficulties arise within families.
Look to oneself first.
The same can apply, of course, with liking behaviour in others. Usually the basis of a good and firm friendship.
