Sibling Rivalry
Whoever said there are two things in life that are certain - Death and Taxes - really should have added a third one to that list: Sibling Rivalry. Unless you come from a family that subscribes to the old Chinese rule of having one child, chances are that you have experienced the ugliness of sibling rivalry in your own family from time to time. We do expect that youngsters will exhibit this undesirable behavior during their childhood but we certainly don't expect grown adults to show this side of their immature psyche in times when family members should be pulling together & cooperating with each other after the death of one or both of their parents.
