Sia means "Helper" in Hebrew, and it's an uncommon name. If you have a friend named Sia, chances are she's a sweet, eccentric girl who loves to help others, even if it hurts herself. She's creative and funny. Take this friend, and don't ever let her escape. She's a rare one who will stick with you for life.
Without Sia, I don't know where I'd be. She's such a sweet friend.
