Learning astrology from experience.
This aspect happened last Monday: Mercury trine Saturn.
Mercury, the planet of communication, the messenger, was in the 8th house of death, transformation, other people's money and investments while Saturn, the planet of structure was in the 3d house of communication.
Clearly it had something to do with communication: Mercury is the planet of communication and Saturn was in the 3d house. But Saturn also makes communication serious and structured.
Looking back, following happened: I talked with a guy that invited me to a group meeting that I had not attended in a long time, and they wanted me back. The meeting was the next day.
