Yes,it is possible to have love at first sight. But we need to be further clear that are we in love or its just an attraction or how the person will response. It is really amazing to have relationship in first impression. life is much more simple if you just view it as simple. Relationship often starts from the begging of hi , hello. Every day you meet lots of people and you are amazed about their behavior. You should be more precise about the relationship but how is it possible? it is my belief that people should make their relationship so clear from the beginning. If you consider someone as your friend you must behave with him like that relationship. It is not good to behave with him like your dreamed one and finally left him by telling him as your friend. You should spend a great time with the person you want to make your life partner. You can be ensure about his behavior and his intention by making chat with him. Yes it is not the only way to make your life more precious about your relationship but it can help you to find some more and find in dept of your dreamed person. At first try to know him from chatting on different zone then try to ensure that the person is giving time to you and caring to you. If it is yes then please go for relation. Happy Relationship.
