Because

I don't know why 

I feel as I do about you...

maybe it's how you love me,

how you talk to me,

how you feel me.

Maybe, it's how you know me,

and speak to my heart,

that I feel you as well.

And then I think:

I know why I feel

as I do about you...

it's because you're my mother.

The bond is there 

and the connection is real.

And I love you.
