Cool thread, wish I had a brother or a sister. My father was in the Vietnam war, was totally against guns most of his life. Now that he's older he seems to be okay with them, but doesn't know a damn thing about it and has no real interest to 'Learn' or be taught.
My mother, she's not against them but not comfortable around them. Funny how it's all worked out, but whatever - I love guns and my kids have a great interest - I'm teaching them when they ask or talk. I allow them to bring up the conversation and don't try to force it on them. I think it works pretty good that way. Wish my wife would be more willing to learn.
Oh sorry, I know you asked for siblings, but I liked the thread.
