What are the reasons -Why you like/love someone?

Simplicity, openness and helping nature are the qualities I appreciate in others. The people who have some proud attitude then I cannot be drawn towards that person.

Anyone, who takes and accepts as I'm and not demanding,is a lovable one for me.these qualities make me fall head and shoulders on tht person.

I agree, many a times we feel that if someone is helping us, he/she is a good person, but personally I take everything with a pinch of salt. If someone is very very helpful, certainly they have some motive or hidden agenda for which they might ask for a return favor. Like you have already said. Most human relationships are based on the idea of give-and-take. But it is certainly not true in every case...there are people who go on giving but get very less in return..this is in the context of friendship. But there are no reason why you like a person but certainly there could be reasons why you dislike a person.
For me one reason to dislike a person is one who is nosy..one who keeps interrogating others for no reason, and the other one is one who pass comments or criticize others because they are born critics. Such people get pleasure by making others feel bad about themselves.

Love is an emotional tie. I don't think this is done. Love happens and is not done. The question is what generates love. I feel that everyone has some image of beauty and loveable object or person in his mind. When the object and person resembles or corresponds to his mental image, the love happens.

Sandhya- Generally the mental image of lovable object or person is that of opposite quality. A weakling desires strength. even an ugly person like a pretty face. The oppoite gender also is lovable. It is not that anyone would perceive of beauty as something that matches his own characteristics. Often a man likes the qualities that he himself does not possess.

I dont think there is any set reasons for liking someone...You like someone you have not met simply because there is something about them that attracts you and to a certain extent you feel that you have something in common with them, the same is the case when you get repelled by some people because of certain characteristics they posses. No matter how nice they are you end up disliking them because you dont like the way they interact or come across in public. Many a times I have felt that first impressions are right afterall in judging a person...

Love is love, it just happens. There is no reason to love a person.

The question should be why we dislike someone! I love/like everyone unless someone proves me wrong.

Helping nature always attracts others. So if someone is doing something for you without taking anything from you then naturally you get attracted towards the person.

There would be some qualities in a person that we begin to like or love and that's where it all begins. Admiration.
