By "do so little for you" it really means someone who doesn't meet emotional needs you have deep down inside, reciprocate your love or service, or let you know you are deeply cared for - NOT by our society's means either (i.e. material things) but doing it in the way YOU genuinely respond to.... I have love to give regardless of my well being....Period
I usually don't care much for sappy quotes, but I always need to be reminded of this. Coveting is ugly, and, if left unattended, grows into jealousy. And jealousy can grossly interfere with God's plan for your life, but, even worse, it can interfere with His plan for someone else's life.
One of the secrets of life is that all that is really worth doing is what we do for others. ~ lewis carroll
