When asked to point out one or two things that are most important to themselves, many put friends ahead of homes, jobs, clothes and cars.

A true friendship carries a long history of experience that determines who we are and keeps us connected. It is a treasure we should protect. Unfortunately, the better friends you are, the more probably you’ll have disagreements. And the result can be what you don’t want ---an end to the relationship.

The good news is that most troubled friendships can be mended. First, don’t let your pride get in your way. Most of us can forgive each other when differences are brought out in the open. Second, apologize when your’re wrong---even if you’ve been wronged. Over the course of a friendship, even the best people make mistakes. Sometimes, it may be best if the wronged person takes the lead and apologizes. When you apologize, give your friend a chance to admit that he has been wrong also. Third, see things from your friend’s point of view. And finally, accept that friendships change as our needs and lifestyle change. Making friends can sometimes seem easy. The hard part is keeping the connections strong during the natural ups and downs that have an effect on all relationships. My suggestion: consider friendship an honour and a gift, and worth the effort to treasure and nurture.
