Iconoclast....Sorry to hear your step son seems so unappreciative. If it is any consolation to you, I have a friend that experienced almost the exact same thing with his step daughter. But, guess what? He continued to show her the kind and compassionate human being he is, and by the time she was 21, she was treating him like Dad. So don't give up. Your loving kindness may still pay off.
jamie...sounds like a nice Mother's Day for you. (The chocolates sound especially nice....chocolate is my weakness!)
