My younger sister always seems to be stealing the
spotlight. I know my relatives and family try to divide
their affection, but sometimes they make it obvious that they care more towards my sister.

Here are some examples:
-When my uncle gave us money, he gave me $40 and my sister $60.
-When my mom gets mad at us, I get punished.*
-When my little brother wants to play a board game or video game,
he asks my sister first, and if she rejects him, he won't even ask me, he just
won't play the game.

*We are 1 year apart, and she is old enough to be punished, she isn't a toddler.

I have tried speaking to my parents about the situation, but they shrugged it off with the whole,"We treat you equally" thing.

How do I express my individuality and prove my parents and become and equal to my sister? Also, how do I deal with it?
