I am Spring.

I am the agility of a Squirrel climbing a tree,
the poise of a Robin perched in the leaves.

I am the green of the Trees about to bloom,
the red of the Tulips coming soon.

I am the songs of the Birds in the air,
I am the laughter of Children without a care.

I am the smiles of those playing outdoors,
the frowns of those scraping knees on the floor.

I am the chill of the Breeze, just cool enough,
the heat of the Sun, the warmth we all love.

Who am I?
