Bump on the head and I'm free as a bird.

“撞了个脑袋，就像是突然变成了自由的小鸟一样。”

To fly in the sky and feel as free as a bird.

像鸟儿般自由地在空中遨翔。

No, why? Then, free as a bird. What's up?

没有啊 怎么了 那么我没事了 怎么了？

So I just text him that he totally missed his chance to talk to me and that he could be free as a bird and just went home.

所以我就发短信告诉他 他完全错过了和我说话的机会他可以像鸟儿一样自由自在 直接回家。
