Appreciation is another word for this,
That warm and fuzzy thank you that spills out when a friend does something nice for you.  
Gratitude is what you feel when someone is there for you.
When you fall, those are the people that help you bounce back.

Without them you would be lost.
Stuck in an ocean full of people that don't feel “just right.”
Spinning endlessly; not knowing what you're looking for.
Until you find your best friend, the perfect glass slipper.

Sometimes you have different slippers.
Depending on your day, a pair screams your name.
Knowing exactly what is best to make a bad day, a good day.
Gratitude is what you feel when the knots you’ve had in your stomach all day;
Finally go away.

This is what friends are for,
Open arms like a open door,
Whatever you need; ready for you.
So perfect they don't even need a clue.
