Computers crash, software develops unexpected glitches, traffic jams ensue, telephone service snarls up, letters get lost on the mail, machinery breaks down, new projects fail. Ah, yes, the trickster Mercury is up to his old pranks again.
In general the effect of Mercury retrograde is annoyance. Little things get snarled up and a low-grade frustration emerges. Anything involving communications, verbal activity, technology, short trips and journeys, primary education, and siblings can be affected.
What is this Mercury retrograde period good for?
It is definitely a very good period for some actions. No time is completely bad for anything, there is a reason in everything happens.
The key is the reversed direction of movement: take any known Mercurian action, reverse its flow, consider the keywords "re-doing something", "double-checking", "finish the old projects" and there you are, you've found the good side of Mercury retrograde.
Above all, be generous and compassionate: you are already aware about the influence of this period, but the others aren't aware of it or there may be uncontrollable events. That's why you should have more diligence with the others and give them some more time. It'll be your mental health that you'll be sparing actually.
