What you are talking about may be the cause of many things. 1) The person you are referring to is going through an emotional period at the current time. 2) The person you are referring to is going through a period in their life where they are experiencing new or high amounts of hormones e.g. puberty (this may also be caused by the side effects of any new drugs that have recently been taken, but do not take my work for direct drug and medical advice, I am not a doctor). 3)The person you are referring to may have a condition called Skitsophrenia (although this is unlikely I think it is what you are talking about), this is a condition that means you have multiple personalities, and one moment you may be acting very kind and nice and the other you could turn into a madman. Although this is an aspect of Schizophrenia, this is not the sole effect of the condition. Although these are the most commonly known causes, there are many others and for future information you may want to ask someone with a full degree in this field of medicine. SOURCE: My own knowledge
