Excuse me, but can I be you for a while?是什么意思？

打扰一下，可以耽误你一会吗？？
这是很简单的一句话

歌曲Silent all these year里面的一句歌词：

Excuse me but can i be you for a while
　　My dog won't bite you if you sit really still
　　I got the anti-christ in the kitchen yellin at me again
　　Yeah i can hear that been saved again by the garbage truck
　　I got something to say you know but nothing comes
　　Yes i know what you think of me you never shut up
　　Yeah i can hear that
　　But what if i'm a mermaid in these jeans of his with her name still on it hey
　　But i don't care cause sometimes i said sometimes
　　I hear my voice and it's been here
　　Silent all these years
　　So you found a girl who thinks really deep thoughts
　　What's so amazing about really deep thoughts
　　Boy you best pray that i bleed real soon
　　How's that thought for ya
　　My scream got lost in a paper cup
　　You think there's a heaven where some screams have gone
