So I am the type of person who likes lists. I like to make them and I like to check them off. I have to confess that I have been trying to do that in relationships (not to mention everyday life, some of which requires an agenda -- writing things down and actually getting them done). My errant thinking consisted in thoughts that there was a "right" way to be in a relationship or that there was a cookie-cutter mold that I and this other person were supposed to fit into. That includes both friends and family.
I am learning that I can't put relationships in a box, just as I can't put people in a box. Limits are good, and confinement is bad. Confining someone else to our own opinions and thoughts of them is like putting a goldfish in a small bowl. Our knowledge of them (and theirs of us) only grows as much as we will let it. And if there is no room to grow, whatever we have boxed in will eventually die.
Relationships are so much more than a list -- they are the stuff our lives are made of. They may last until death, or they may be given to us for a shorter time. What I am learning is that I should enjoy them for the gifts that they are.
