It has been truly said that once a Romeo is always a Romeo it doesn't matter what it use to be earlier once he started to love someone then he will be always a Romeo. It doesn't matter to him that what the world says bit he is going to do what his heart says to do. It is very Bad disease if you are in it than you can't come out of it easily.
There is my friend who is suffering with such a disease and he is very severe on this disease, because once a Romeo is always a Romeo. He use to do very annoying things which are just out of mind.
