Happy Birthday To Who?

15 year old, Gabe Fredrikson, has five sisters who don't understand him. He wishes that he had at least one brother but his parents aren't fond of boys so they don't pay much attention to him.
His sisters:
-Sydney, 17 years old, Smart and really talented at the piano
-Claire, Gabe's twin sister, really shy but is amazing at singing and playing guitar
-Vivian, 11 years old, a little brat that gets anything she wants by whining
-Hannah, 14 years old, loves sports-Soccer, volleyball, softball, tennis and basketball- the most understanding out of the five girls
-Lexi, 5 years old, the cutie that is nothing but sweet and loves to play with dolls.

Warning: There is swearing but I use a "*" to sorta block it out.
Ex: Crap = Cr*p
Except of course, it's actually swear words.
