This may sound trite but one of the things I have tried to hang onto all these years is the sound of his voice, especially certain times.  When he called on the phone and I answered, I can still hear him say "Terry?".  Or when I would ask him a serious question that he couldn't answer, his response was a quiet "I don't know, Terry".

It wasn't the words that were important, its the memory of his voice that I want to keep inside my head because then I can keep a part of him alive inside of me always and forever.
