My main rules are:
Always tell the truth. Nothing to remember, except WHAT REALLY IS, and nothing to hide and be afraid of someone finding out. Believe it or not, I was actually kind of a latecomer to that rule, but since my early 20s, I've learned its inestimable value.
Always TRY to live up to my own highest ideal of ethical behavior. Seems to me that's the easiest way to be happy, without [too many] regrets. Wish I'd learned that one a little sooner, but just glad I finally did learn it.
And try to make sure that anything I say to another person is a) true, b) kind, and c) necessary.
And yes, unconditional love is the name of the game at my house; me for my husband and son, them for each other and for me. It took me a little while to get it thru to my son, that he could always tell me ANYTHING, because no matter what, I will always love him, always be on his side, and always be his best friend and biggest supporter. Maybe that's why I was the first one in the family to whom he "came out," once he finally figured out that he wasn't a "stock heterosexual." Not sure he's fully decided if he wants to go to one side or the other completely, but he knows I love and support him, NO MATTER WHAT. I did ask him though, even if he decided he was completely 100% gay, if he could refrain from "swishy" behavior. He rolled his eyes at me and said "Do I LOOK swishy to you?"

He really doesn't, which I guess is why he actually had to "come out" in words. 'Course he does sometimes wear a t-shirt that says "Taste my rainbow. "
