Mercury retrograde
Mercury runs the wiring of ordinary life — messages, schedules, signatures, the commute, the device in your hand. When it turns retrograde, that wiring asks to be checked rather than trusted blindly. Crossed signals, rebooked trains and resurfacing old conversations are simply the season reminding you to slow down and read things twice.
Good for: Unbeatable for revising, editing, catching up, and reconnecting with people who drifted out of reach.
