My dad prefers step sister over me?

THATS WRONG JUST TELL HIM ABOUT IT BECUZ THATS HOW MY OLDER BROTHER IS. ITS LIKE THEY ONLY WANT TO BE BOTHERED WITH THE KIDS THAT THEY SEE EVERYDAY AND LIVE WITH. BLINDED BY THE LOVE HE HAVE FOR THE WOMEN SO HE TREATS HER KIDS BETTER THAN HIS OWN KIDS. SAD STOP CALLIN HIM FOR A WHILE AND THAN HE WILL CALL U AND THEN TELL HIM HOW YOU FEEL
