When I was a wee, young airman and old Staff Sergeant gave me the best advice. He said, everytime a man thinks with the head of his d*** all it does is get him into trouble.
My Father was a lifer in the USAF. He was a tough bird that started out in the Army and when the USAF was being formed in 1947 he switched services. He gave me three bits of advice. First, “Don’t ever F... the help.” His second was “never drink a man’s whiskey and take his generosity and try to f... his wife.” The third was “always wear protection” because at a military base one cannot trust anyone. Well, over the years all three bits of advice were heeded and kept me out of a world of hurt.
