I am the oldest and deserve to be married first. My little sister has to wait. Tradition matters most and as the oldest it is my responsibility to continue what has been done for generations. We cannot be ignorant or selfish because all it leads to is disappointment. Rachel needs to welcome reality and stop kidding herself with the illusion of love. It will only hurt her in the long run.
Rachel has her head in clouds and is in oblivion instead of reality.
