What it means
The past is remembered in detail — smells, words, who said what. Decisions are made by feel, and logic adjusts afterward. It's easier to talk about loved ones than about abstractions.
The flip side is that thinking depends on mood: on a bad day you can't think, and old hurts replay for years. Criticism is hard to hear as criticism of the work rather than of you.
This isn't about you if you remember the past vaguely and make decisions by cold logic.
How to check it on yourself
Check it against your past — write your answer down before you look at the chart.
If your Mercury is in Cancer
What should match. Recall three old conversations — from five years ago or earlier. At least two you remember word for word, with the tone and the setting.
When it’s not about you. Of all three you remember only the general sense — this isn't about you.
Your sign and house of Mercury — in the free calculation: build my chart. How we check the rest — the site’s method.
