A family vacation trip can be very stressful or it can bring families closer together. The 1983 movie “National Lampoon’s Vacation” portrays the misadventures of the Griswold family as they travel to the Wally World amusement park – a trip comprised of a number of disasters and misadventures. 

Why It Matters

  • Friends share things – loaning a hammer, borrowing a cookbook, sharing carpool duties for the kids. There are limits to the sharing just as there are limits to the friendships. Each person has their own space and their own outside set of attachments. The friendship bond is just one of the connections each person has in their life.
  • Husband and wife share a deeper, more complex connection. They are intimately involved in each other’s lives. In many states the property is owned jointly and not by one or the other. In the ideal situation, finances are comingled and managed by the couple. Of course, there are other bonds, primarily to other family members.

    The bonds of marriage are different from other familial bonds because it is a legal contract recognized by the government. [Figure2]


  • Infants and small children are in a dependent situation. They cannot provide for themselves and can manage much less of their daily lives than others in the family. They rely on what physical and emotional support is given to them by others in the family.
  • In each of these cases, bonds of attachment may be broken. Friends may move out of the area to take a new job, husband and wife may dissolve their marriage, children grow up and are able to manage on their own. The old bonds are broken and new bonds and relationships form.
