While I somewhat agree with what he said, he is lousy at delivery and timing.
The "pink cloud" is what some people call early sobriety where we are all excited and have a lot of enthusiasm going for us. It's easy to say "I'm done with drinking and won't poison myself with that stuff ever again." After a while, that enthusiasm tends to lessen and we really realize that living a sober life means we must constantly be vigilant. Not scared or fret and worry, but vigilant. Making the right choices and not putting our sobriety at risk. These are things we will have to continue for the rest of our lives. I guess another way of putting it would be...the "new" wears off.
