Theoretically, I suppose it balances out. In real life, it often doesn't seem that way. When Mercury is Rx, these things become snarled and problematic. Unforeseen problems show up and have to be handled somehow. The time of Mercury Rx can seem aggravating, confusing, disjointed, stagnant, and frustrating.
Transportation problems occur.
All things concerning information, communication, thinking, movement, and travel run into problems, mix-ups, and delays. For practical reasons, it's wise to keep this. Important decisions should be reconsidered but not finalized when Mercury is Rx. Be ready to take in new facts, view new angles, consider previously unseen complications, and handle misunderstandings or incomplete data. The same goes for reconfirming important appointments and other plans, especially during the time of Mercury Rx.
