You are my heart, and I can't live without you.

你是我的宝贝儿，没有你我无法生活。

I am your appendix, you are my heart.

我是你的盲肠，你是我的心脏。

Because you are my friend i would do for you all that my heart and my soul and body are capable doing.

因为你是我的朋友，我将为你做心灵和身体允许我做的一切。

Although we fight, we bicker, delight or even anger, you are my best friend forever in my heart.

就算是吵架也好，斗嘴也好，开心也好，出气也好，你永远是我心中最好的死党。
