You what, I what idiom?

Life and death,

You respect my love,

You, um, I like it,

You come and I go,

You support me,

You come and I go,

You are the east and the west,

You pity me and love me,

You fight with me,

You push me and let me,

You brag, I applaud,

You sing for me,

You long for my love.
