Alright, alright, I'm getting to it. Don't rush me sonny. Awfully cynical, I know. Nevertheless, while the truth is great entertainment for nosy outside observers, it is almost always never in the interest of those involved. Truth is often ugly and unkind.
Lies are much more flattering and readily digested.
If you want your relationships to last, whenever your mate asks you whether if she looks like something the cat dragged in, you tell her no. Whenever your mate asks you if you thinks she's gained a little weight, you tell her no. You tell her that you were just about to ask her if she's lost a little weight because you were worried if she's been eating well. If your mate ever asks you if you think a particular woman, any woman, is more attractive than she is, you tell her no. You tell her that she is without a doubt, the most beautiful woman you've ever seen.
