Mercury in Third House
Mercury: If the lord of the 3rd is Mercury or Mercury is in the 3rd house and dignified or received, then you may be a quick study able to pick up on various subjects easily. You are good with book keeping and documents and tend to be fortunate in legal matters. You run into alot of tangents when moving about town and rarely go straight from point A to point B. You are agile and quick to pick up on subtle opportunities in your vicinity. You may have oratory and writing abilities. If Mercury is afflicted or debilitated then you find it hard to stay on schedule and may be little more prone to suffer run-ins with criminals and police, particularly if the planet doing the afflicting is Mars. There will be acrimony between siblings and a breakdown in communication from time to time.
