Three siblings.
The oldest being a 26 year old girl,
The middle child being a 18 year old boy,
And the youngest being a 17 year old girl.
The 26 year old living her life as a professional skater, and her 18 year old brother thinking of being a professional volleyball player, as for there younger sister she wanted to do it all.
Being taught how to skate by her sister who was 8 years older than her, she never loved anything more. Then one day her brother who was just a year older than her taught her how to play volleyball. She was completely hooked, two things she loved most but her parents told her she could only do one.
Not being able to choose what she wanted she decided to keep one of them a secret. Almost every night she would sneak out to pursue her love of skateboarding, and in the morning she'd wake up and go to volleyball practice.
Her brother knew of this but never told his parents despite worrying for his younger sister, but one night he decided to take it into his own hands.
