the cause?

I've been thinking lately about just what causes the feeling of happiness for me.  It's simple things usually.  Singing along with a favorite song.  Time with my favorite people.  Cool mornings and warm afternoons.  A wagging tail.  Clumps of blossoms.  Leaves changing.

Tonight we had the first fire in the fireplace for this season.  I'd forgotten how much I like that feeling of warmth blowing on my chilled skin.  Yet another moment of happiness.
