You should hear some of the things she tells me sometimes late at night when she's worrying about you.

Like about how she wishes she could go back ten years and all of the things she would have done differently then.  Or about all the regrets she has.  Or about the thoughts that sometimes tell her how bad of a mother she is.

It breaks my heart to hear her say things like this.

You should see how you break her heart when you do things like this.
