Benefits of "Mental Noting" during positive events?

I've been using [Mental Noting](http://www.insightmeditationcenter.org/books-articles/articles/mental-noting/) to improve my handling of anxious thoughts and emotions but I ran into a strange situation today. Most of my thoughts have been neutral or negative, and mentally noting such thoughts has allowed me to disassociate myself with any such passing clouds in my mind so that I can continue about my day. However, after a physically gloomy day today I saw the sun come out and light up the city. I initially felt very happy seeing the sun shine across the buildings but then my habit of noting came in the picture and I felt a distance between me and the emotion (just as I would an anxious emotion). From what I understand, this is what the practice calls for me to do in any type of event. Is there something I'm doing wrong or missing here? It seems that long-term noting will cause me to put a distance between pleasurable moments just as it would with negative ones? Why would I want this? I enjoy such emotions and whatever pain I experience from them being so fleeting is worth it. I'd rather maintain the duration by which I experience such moments, not shorten it with noting. I'm not sure what perspective to have in such cases and whether there is some greater benefit to continuing to do this for all situations?
