Love at first sight

Does love at first sight really exist or not? There are many examples in which people say that they have fallen in love after seeing their love one first time. Some believe that love at first sight exists and some says that it is just a kind of strong attraction. Many people have accepted their first sight love and are living happily today with them. Others have just forgotten this love as beautiful moment. I have also a similar kind of attraction in college days. A girl from college was so attractive to me that I just fall in love after seeing her only one time. However, the truth was deeper then it looks to me. The girl was really very-very beautiful and half of college had fallen in love with her. Now it was really a love or just some kind of attraction towards other sex. These questions are very difficult to answer with our normal thinking levels. There are few experiences in life which make lot of impression on us; love at first is like this only.
