Well hello, 
Sweet peaceful happiness.
The brief moments in your life, that come and go.
Moments spent with someone that truly gets you, although this person is long gone.
Moments standing in your backyard looking at that big messy tree. The tree that makes you realize that seasons are going by.
Beginning in early spring with it's small bright green leaves. As the weather warms the flowers bloom. Flowers that later fall and litter your lawn.
As you look at these flowers you realize that next year at this time these flowers will have been long gone, but new flowers will lay in there place.
And so it goes, brief moments of pure sweet happiness, then lessons. All bringing you forward, and bringing a smile to your face.
