Passenger 的bloodstains中有句”feeding off the crumbs of our heart”,请问是什 么意思呢? 查了feed off, crumb,但整句意思还是不懂@@ 这段歌词: I'm waiting and you're waiting But this train's not gonna come Your voice has started grating And I hate what we've become So theres no future at this station We're just feeding off the crumbs Of our hearts 谢谢!
