I used to say, "Don't know what Mercury Retrograde is? Great! Carry on!" when coming across someone who wasn't yet aware of it, previously perceiving it as a big pain in the ass and wishing I, myself, could enjoy the "ignorance is bliss" route. Yet over the years of moving through it with conscious awareness and deepening my understanding of its purpose, I now encourage people to read up on it so they can use it to their advantage.
