you and Lily were born with an emotional connection between eachother as whenever you cry she cries to and vice-versa. Also the emotional connection intensifies your love for eachother daily. Also whenever your at school or out in public Lily will act cold and emotionless towards you so that nobody knows that you have a connection with eachother which causes you to cry and in return causes her to cry aswell since eachtime you cry she ends up crying aswell
