I like Gemini's but how come some get angry so easily?

Is he from the second decan gemini?? second decan geminis are pretty jealous & possessive. More faithful to who they're with, GOT the good looks but can be evil. He's messing & testing just to see how long you'll last with him. Gemini LOVE to argue especially gemini from the 2nd decan, he probably just want to argue because that's what turn us geminis on.
