There are different kinds of lovers here on planet Earth. There are the kind when they see a guy/girl will know he/she is the one. This is what happens in the movies... The act mentioned above is highly risky, don't try this in real-life (or try maybe under parental supervision). Then there is the kind like me who watch all these crazy youtube videos to find whether it is true love or not, and miserably fail at it. Even after so many such attempts I still don't know if I am doing the right thing or not. It might seem silly for you to read this, perhaps you might never understand and you will be least bothered, but I am sure there is someone out there who will be going through the same like me, and he/she will know what it is like to be in this situation.
