Tom: What happens when you fall in love?
Summer: You don't believe in that,do you?
Tom: It's love, it's not Santa Claus.
Summer:what does that word even mean?I've been in relationships,but I don't think i've ever seen it.There's no such thing as love. It's a fantasy.
There is no such thing as:没有...的事情;...不存在
There is no such thing as a free lunch.
世上没有免费午餐之类的好事儿.
