No more gifts from me. If I ever felt obligated to give a gift, I would give something to charity on behalf of my DS.
Quick story: Before my dad passed away 23 years ago, he and I had a heart-to-heart talk. He thought he was a horrible dad. I thought he was great. The last conversation my brother had with my dad was my brother yelling at my dad in front of (my brother's friends--showing off) friends. When my dad visited me later in the day, I could tell something was wrong. He told me that he was yelled at and felt humiliated.
People would see my brother go into the cemetery grounds at night and stay until the early morning hours. He would scream and cry like a baby while laying on my dad's grave--regret can kill a person.
I always think of this story. My OS will have to learn on his own --how valuable people really are.
Live your life! (I know, easier said than done)... Try to surround yourself with people who truly care about you! Take care of yourself!
