My husband is generally a happy go lucky person, but suddenly with no big reason, he becomes too angry that he destroy the surrounding objects and scream loud. Earlier i thought its a man ego kind of thing, but he gets angry for such a little reason which don't even make sense ... And after an hour around he become very normal like nothing happened . He has very vast and instant change of reaction that even I can't understand.. And it happened from last 4 to 5 years. I know him from last 9 years. He was okay that time.
