Live your life with arms wide open

Shasta stood on a limb of an old oak tree her arms outstrectched. I suppose to a simple passerby it would look as though she might be trying to kill herself with the stance. Although, they would also notice she was only a few feet above WATER not ground.
With a deep breath Shasta closed her eyes. After a moment of silence her eyes shot open and a smile spread across her lips.
GO! she yelled and jumped from the branch moving her arms in front of her head and making contact with the surface of the lake quickly moving to the murky depths. She did a somersault under water and pushed off the soft soil and swam back to the top. She let out the breath that had been in her lungs for a while and flung her head back getting her wet hair out of her face. She treaded water in place for a while while she smoother back her hair and took in some sweet breaths.
Time for round 2. she said with a smile and started back towards shore.

Shasta walked out of the water and flipped her hair back over her shoulder and strung it out and then flipped it back again behind her head.
She looked up and saw the boy sitting on the bench. She smiled at him and waved and headed back up the tree, she was already half way to the branch when she called back down to him.
You wanna come? It's a jolly good time. she said with a really bad british accent.
She finally reached the branch and tugged off her soaked tee shirt to reveal the top of her purple one piece swimsuit.
She looked back down at the boy and smiled as if to say 'well, are you coming or not?'

Shasta smiled at him and said
My name is Shasta, it's nice to meet you.
She smiled then grabbed his hand and said held up her other hand, put up one finger, then another, and a third took a quite breath and then jumped dragging him with her.

Shasta let go of his hand when they met with the surface of the water and stayed submerged for a while after him. Then she heard him yell something, she thought it was "awsome"
She swam up to the surface and flipped her hair back treaded water and smiled at him.
So did you have fun? Wanna go again?

Shasta smiled at his reaction. She took her time swimming back to land on her back though, enjoying the afternoon sky, and even the EXTREMELY brisk coldness of the water, it all mixed together to create an intoxicating situation. When she finally reached the edge she crawled out and raced back to the tree. When she looked up she saw him shirtless and smiled, sensing time to mess with him.
Better watch it. Seeing a mans skin is against my religion! she said wearing a completely serious face as she made her way up the tree. She finally reached the top and looked at him, still completely serious and said
Well? and stood there waiting for his reaction.
