     Attending builds friendships and acknowledging builds friendships. Friendships require equality and

friendships require loyalty from friends. It takes three years to build true friendship.

     In most cases, the development from acquaintance to friendship occurs gradually. We reach out to

offer friendship by offering a potential friend caring, listening, talking, sharing, accepting, and affirming. It

takes time and effort to build friendship. They are built slowly, slowly, slowly…yet, nothing can add more

to your life than having truly intimate friends. "Just friends" is a goal which is well worth pursuing!

     Self-disclosure is usually the first step in establishing a confident. And it is scary because of the

potential rejection factor. Do it anyway!

     Listening and acknowledging builds friendships. Often when your child, lover/partner, or friend tells

you a story or voices a complaint, he/she is just asking for acknowledgement. This does not mean that

he/she wants agreement or compliance; it merely indicates a desire to be heard and understood.

     Many conflicts in our personal relationships can be avoided if you take the time to acknowledge

others' feelings and points of view.

     Listening and attending builds friendships. Paying attention to someone is called "attending".

     It means that your ears, your eyes, your body and your feelings are all focused on that person at one

time. Attending is a very important part of any relationship. Looking at and focusing on another person

shows that you are "there for him/her".

     Friends are equal. Without equality, you can't have a close friendship. Friends are loyal and

trustworthy. No one can confide in someone they can not trust to be loyal and to keep his/her secrets.

     Allow time for friendship to grow!
