What is the warning sign of Capricorn?

Both are competitive and prone to conflict.

Capricorn people tend to feel a little jealous of Aries' optimism, but it is not necessary. Capricorn people also have their own happiness. Aries people often give people the impression of selfishness, because they always follow their own inclinations without much consideration. They really should remember to think twice before you act. Capricorn's selfishness stems from their disdain for others, and they only care about their own dignity. In any case, selfishness is selfishness, which is very bad in any way.
