1. "Always" and "never", and similar absolutist words, are very, very, very risky, ESPECIALLY when linked with promises of human beings! How about "will sincerely try" or "will do my earnest best"?
2. IMHO, you can't go wrong with the basic "golden rule" (treat others as YOU would wish to be treated). This has been found in virtually EVERY religious and ethical system worldwide.
3. The Unitarian Universalist principles (see http://www.uua.org/visitors/6798.shtml) might give you some more ideas on "good rules"----
* The inherent worth and dignity of every person;
* Justice, equity and compassion in human relations;
* Acceptance of one another and encouragement to spiritual growth in our congregations;
* A free and responsible search for truth and meaning;
* The right of conscience and the use of the democratic process within our congregations and in society at large;
* The goal of world community with peace, liberty, and justice for all;
* Respect for the interdependent web of all existence of which we are a part.
And if you don't mind something a bit wild, here's The Eight "I'd Really Rather You Didn'ts" of the Flying Spaghetti Monster (deity of the Pastafarians; see http://en.wikipedia.org/wiki/The_Gospel_of_the_Flying_Spaghetti_Monster)
(Lettering in quoted Wikipedia entry has been sanitized here to avoid a possible conflict in Yahoo community standards.)
1. I'd really rather you didn't act like a sanctimonious holier-than-thou a$$ when describing my noodly goodness. If some people don't believe in me, that's okay. Really, I'm not that vain. Besides, this isn't about them so don't change the subject.
2. I'd really rather you didn't use my existence as a means to oppress, subjugate, punish, eviscerate, and/or, you know, be mean to others. I don't require sacrifices, and purity is for drinking water, not people.
3. I'd really rather you didn't judge people for the way they look, or how they dress, or the way they talk, or, well, just play nice, okay? Oh, and get this into your thick heads: woman = person. man = person. Samey = Samey. One is not better than the other, unless we're talking about fashion and I'm sorry, but I gave that to women and some guys who know the difference between teal and fuchsia.
4. I'd really rather you didn't indulge in conduct that offends yourself, or your willing, consenting partner of legal age AND mental maturity. As for anyone who might object, I think the expression is "go f*ck yourself," unless they find that offensive in which case they can turn off the TV for once and go for a walk for a change.
5. I'd really rather you didn't challenge the bigoted, misogynistic, hateful ideas of others on an empty stomach. Eat, then go after the b!tches.
6. I'd really rather you didn't build multi million-dollar synagogues / churches / temples / mosques / shrines to my noodly goodness when the money could be better spent (take your pick):
1. Ending poverty
2. Curing diseases
3. Living in peace, loving with passion, and lowering the cost of cable
I might be a complex-carbohydrate omniscient being, but I enjoy the simple things in life. I ought to know. I AM the creator.
7. I'd really rather you didn't go around telling people I talk to you. You're not that interesting. Get over yourself. And I told you to love your fellow man, can't you take a hint?
8. I'd really rather you didn't do unto others as you would have them do unto you if you are into, um, stuff that uses a lot of leather/lubricant/vaseline. If the other person is into it, however (pursuant to #4), then have at it, take pictures, and for the love of Mike, wear a CONDOM! Honestly, it's a piece of rubber. If I didn't want it to feel good when you did it I would have added spikes, or something.
