Dear Ann Landers, I am 65 years old and the eldest sibling of five. This is my problem: My younger brother, Bill (number 3) came out of the closets a gay man about ten years ago. This didn't surprise me, I had suspected it for quite a while. All my family want our father to know, and I am against it. Our father is 87, raised in a small town all his life, and would be devastated to learn that he has a gay son. Bill seems to be indifferent. When Bill does visit, he leaves his partner home, which is out of state, and the family acts as if everything is normal. Dad is happy and I want him to stay that way. We all love and support Bill, but I need some advice on how to handle this with my siblings. - Concerned son
