When we see the sins of another with an ease, with a simple statement to ourselves, "they sin there," followed only by a humble realization that we, too, could do that sin. When love is there to not only forgive the person in our minds, but to think to pray to God for mercy in the sins of us all- mercy for the friend who has sinned, mercy towards ourselves for our sins, mercy for the nature of sin we can't escape.

That's it. That's the line we draw between discerning a sin and judging it.
