Why do you think my dad favors my sister?

Stayinganon
My dad has always favored my sister. She's 5 1/2 years younger than me but I think back to when I was in her age and he never treated me that way. I'm a really good kid if I do say so myself, never did drugs or drank in high school, even at parties I remained sober and took care of everyone else. I made good grades and I'm in college, I mean I'm no genius, but I've always been above average when it comes to grades. This is not just an older sibling whining the younger one gets it better, because my mom doesn't do this, only my dad.

My sister is the most difficult person I have ever come across. She's moody (maybe bipolar?) and annoying. She snaps at the smallest thing and doesn't understand boundaries. She's rude and doesn't care for other people's feelings. My dad admits this, but yet does everything for her. Anything she asks. He doesn't buy her whatever she wants but he does anything she wants. He can be in a completely different room and he runs when she calls. I never say anything because I'm embarrassed. My dad and I are closeish but we never hug it say I love you. If I ask him to do the smallest favor he tells me to do it myself or complains about doing it for five minutes. He never acknowledges anything good I do but if my sister does anything remotely "good"it's a fucking miracle and she gets rewarded. I'm never good enough.
