My good friend Tess said this on the subject of relationships:
Relationships are like sticks.
You enter the wood and find a nice stick. You pick it up and walk with it a while.
Then you spy another stick that looks better than the one you have.
You throw your stick away and walk with the new stick.
A while later you see another stick that looks better than the one you have.
And so it goes on.
There is always a better stick than the one you have.
You discard and pick up in search of the perfect stick.
Then you look up and find you are coming to the end of the wood
And you do not have a stick.
Suddenly any stick will do.
