Someone you would set and listen to their problems and they listened to yours. They were friends. But when you left they were gone. Now you feel a void for that kind of confidant.
I had good friend whose family was very close with ours. Our small children were good pals. We did things together. Fishing, camping, going to dinner and a movie. He had a drinking problem. Two drinks made him drunk. I once saw him pulled over by the police near his home. I stopped and pleaded with the officer to let me take him home and he agreed! I saved him jail, suspended license and thousands of dollars.
Anyway, when I left he shunned me big time. Like others who shunned me the most severely, he was a marginal witness.
