do you think that a person must look for hapiness in other person??

No. I beg to disagree with that. A person should not look his happiness in other person or in certain things. Happiness must start with one's self. We should be grateful of our life and this gift of life is enough for us to be happy. It is wrong to depend our happiness to a certain person when in fact you have your self to be happy with. It is a matter of gratitude and positive thinking. Have a nice day!
