Void for Vagueness?

Last night Red declared a new rule. I am not to allow one or both of our dogs to remain outside too long, or I will be punished. This rule came about because yesterday morning I let the youngest of our two dogs outside and left him outside for about 15 to 20 minutes. The length of time was not excessively long, but it was chilly and he's a small dog. When I let him in, I apologized for being a "bad mommy" and assured him that "daddy will punish me for it later." I thought Red was napping at this time and had no idea that he'd overheard my little one-sided conversation.

Anyhow, last night while lying in bed, he informed me that he had in fact heard, and that from now on I really would be getting punished for such infractions. I remained quiet and accepted his pronouncement.

I have to admit though, that the compulsively rule-observant part of me immediately started coming up with questions. I like to follow rules - all rules - to a T, and for that to be possible, there must be a "T." There must be a strict definition of the rule so that I can remain firmly within its limits.

How long is too long? I wanted to ask. Is it conditional on the outside temperature? Is there a "relevant range" of sorts within which it is acceptable to leave him outside for "x" number of minutes, or is it directly (or indirectly) proportional to the relative extremity of the temperature? Does time of day factor into this consideration? What is the equation with which I can determine the appropriate amount of time for the dog to remain outside given all considerable conditions?

I know that if I actually voiced these questions to Red, he'd be completely exasperated with me. My compulsive good-girl-ishness almost never fails to stand in the way of him imposing the boundaries and discipline that I claim to want. And I do want them, though I admit that you'd never know it from my behavior.

So I'm not quite sure what to do now, other than resist the temptation to never let the dogs outside at all...
