sth about hot and cold

Katy Perry出生于1984年10月25日，加州圣巴巴拉。由于生活在一个基督徒家庭.因此小Perry很少向其他小孩子一样听一些所谓的世俗音乐，长大的Perry疯狂着迷于Alanis Morissette和Freddie Mercury，但宗教音乐依然情有独钟。于是，当时年仅16岁的Perry在2001年以Katy Hudson这个名字在Red Hill Records发行的一张基督徒唱片。之后，Perry的曲风也慢慢倾向于流行音乐。这首歌的MV一直在[V]台播，很有创意！

lyrics:
You change your mind你改变你的主意
Like a girl changes clothes就像一个女孩改变她的衣服
Yeah you, PMS没错 你就像得了经前综合症
Like a bitch像个妓女
I would know我应该知道
And you over think你仔细想过
Always speak说话总是
Cryptically神秘兮兮
I should know我应该知道
That you're no good for me接近你对我不好

Cause you're hot then you're cold因为你的火热变得冰冷
You're yes then you're no你的肯定变成否定
You're in then you're out你的流行已经出局
You're up then you're down曾经得意变成失望
You're wrong when it's right你颠倒是非
It's black and it's white颠倒黑白
We fight, we break up我们争吵，关系破碎
We kiss, we make up我们相吻，关系和好
You, You don't really want to stay, no你不是真的想留下来
you, but You, but you don't really want to go oh但也不是真的想离开
You're hot then you're cold你的火热变得冰冷
You're yes then you're no你的肯定变成否定
You're in then you're out你的流行已经出局
You're up and you're down曾经得意变成失望
