Rat and Tiger
This is a bumpy ride and certain amount of risk. In order to succeed both must endure.
Both have quick tempers and strong characters. This match may prove a good deal of competition but challenging and stimulating.
Rat initially admires tiger as outward looking and a colourful personality but soon tires.
Tiger cannot tolerate rat's craftiness, schemes and nagging insecurities.
With much compromise from from both parties, this could result in a permanent match in the long term.
