You know you got something wrong, but you can't quite figure out what. It's not unlike adding up a column of numbers and getting a different answer every time. You pore over every detail, but the solution stubbornly resists you. Welcome to Mercury retrograde. Mercury will be retrograde from November 25th to December 15th. Planet of the mind, Mercury becomes a brainteaser when it's retrograde. What you want to watch out for is insisting that the rules still apply and that it's reality that's wrong. Think Alice Through the Looking Glass. Get into the spirit of exploring the ridiculous, and you could discover the sublime.
