I'm so glad you wrote about this topic, it hits a nerve with a lot of people and although often "meant" as an uncomfortable apology, this statement says "I'm not changing and have no part in this disagreement or discussion".  It can be very invalidating.  As difficult as it can be, and we've all been there, it is important to truly listen to what others are saying and validate their feelings, especially when we know we bear some responsibility for the current strain in the relationship.  Most of the time, we know if we've done something that can be hurtful, that's why it's so hard to hear how someone else is feeling.  The value in taking responsibility and showing care and concern for the other person can truly change relationships and lives.  It ultimately pays itself forward and others take the lead in doing the same if you take the time to do this with them.

Another excellent post...
