What makes a best friend special?

What makes a best friend special?
It's not how they do their hair
The music that they listen to
The clothes they wear
It isn't what the eye can see.
That brings another friends pride
But the warm and caring person
A best friend that is inside
It's their gentleness and laughter
the joy they always give
The honesty and kindness
And the thoughtful way they live
What makes a best friend special it is from the every start?
It's the most important thing of all-
It is the love that is in their heart
