When they say,” Love at first sight” they mean it literal when you see someone for the first time and you automatically fall in love with them. I actually believe that love at first sight exists because I was in that situation but sometimes it won’t last for as long. An example of love at first sight would be,” Romeo and Juliet”. Romeo and Juliet instantly fell in love with each other but were forbidden to see each other for Romeo was a Montague and Juliet was a Capulet, but that didn't stop them from seeing each other but eventually threw obstacles and tears lead to their inevitable deaths.
