That's always a thin line that I never understood. Let me change the argument ... I am asking.... What is the correct way to give a compliment??

Some people like oceans, some like mountains, I like attractive women. I will tell a complete stranger that in case they haven't heard it yet today, they are absolutely beautiful and I walk away. No come on, just a compliment. Can a compliment be rude? If you think whistling at an attractive woman is crude, ok. I don't do it but some men do. I can't say that I've ever been in the company of a man that has made a rude comment to a woman because I wouldnt stand for it. Of course it's subjective and you really haven't given any examples, but you've already called it a "compliment." What you sense it being after that is up to you. But if your attempt here is to stop compliments, something YOU call them, then I think that's a problem. As an aside, in the dating book I'm writing, it will be called "It Just Doesn't Matter" and the best example I can give relating to your question, is an evening way back on a roof top bar in the City of Detroit, wall to wall people, and I saw a woman at the bar I had to get to. I waded through all the people, got up to her and said "boy you don't know what I had to do to get here." Her response, "well I liked your arrival, now let's see you departure." Proof that you can be a babbling idiot and if she wants to talk to you she will and you can be the most erudite person in the world and if she doesn't want to talk to you she won't. Did my "compliment" go too far?

I am close to the point of, "Your tits look great. Thank you for drawing my attention to them."

Maybe you are just too hard on yourself.
