OK, first - I was literally laughing at loud at some of you. Thank you!

Second, I agree with the idea that thoughtful, little overtures of appreciation – surprise or not; successful or not – are usually received positively. Indeed, every dom/partner will react differently, and it's Murphy's Law that our attempts will sometimes go awry. However, I have yet to have a decidedly negative reaction from my dom...maybe less than enthusiastic, but not anger or the sentiment that I was usurping his authority. Perhaps mentioning a hypothetical to your dom would clear up any fear or concerns.
