10. Gemini
It will be because already in their sign there are already two, as well as the two children, those born in the sign of the twins can have a double personality. Lunatic and fickle. Irascible and easily irritable. Just as the wind changes, in the same way a Gemini, if a moment ago he was happy and carefree, a moment later, without the people around him understand the reason, changes and becomes snaught and unbearable. But they are also very smart, curious and adaptable to many different situations.
