[你问我答] skip to my lou这首儿歌讲的是什么意思

Lost my partner,
What'll I do?
Lost my partner,
What'll I do?
Lost my partner,
What'll I do?
Skip to my lou, my darlin'.

Lou, Lou, skip to my Lou,
Lou, Lou, skip to my Lou,
Lou, Lou, skip to my Lou,
Skip to my Lou, my darlin'.

I'll get another better one,too.
I'll get another better one,too.
I'll get another better one,too.
Skip to my Lou, my darlin'
还有一些歌词，没写上来。这儿歌本身是表达什么意思，还是纯为了押韵的童谣而已。
