The beginnings of a thought

I am learning. People change. I change. I have been thinking about relationships. I have been thinking about the people involved in them. We all are constantly becoming someone new. We are evolving. How can we expect a relationship to remain the same when the people involved are changing?
I have thought that we need to enjoy our relationships in the moments we are given. And when we see that a friend is moving on, or changing, that we need to evolve our relationship with them to accomodate the new feelings.
And I like this thought. People aren't static. Sometimes they aren't permanent in our lives either. They come into our lives to teach us what we need to learn from them, and they move on, or we do.
People and relationships changing should be encouraged. I like to think that I am someone different from just a few months ago. The change may not be huge, or even noticeable by anyone but me.
When one is changing and another isn't ready to move on in the relationship, then maybe that's how people come and go in our lives.
And of course, relationships require that the people involved work at keeping together.
