Well, no one can understand precisely what someone else is going through, or what they feel ...but I thought I understood more than she was willing to give me credit for, at least at the moment anyway.

But that was not my response to her.  Instead, I said, "So, you say I don't understand you ...and I probably can safely say, you don't understand me.  But what is important is that we both understand God."

God knows more than you or I, about ourselves ...or about any subject.  So, if we just attempt to understand God, then our feelings on any subject, or about each other ...will do quite nicely.
