How to say about love?

Roberto is an ordinary boy who plays with his friends and dreams of flying on a rocket to the stars. For him, the world embodies adventure. And then one day he sees Isabella, a little fan of butterflies, and his heart is filled with a delicate feeling that he did not know before. Roberto is in love, for the first time in life!
But how can I tell Isabella the fact that he would like to tell her so much? After all, these should be some special words. And to convey them to the girl must somehow be special. Maybe shout about your sympathy with the highest tower? Or write on paper sheets, how does he like Isabella, and hang them throughout the city? Or maybe climb into the sky, and ...
Roberto has many ideas, but in the end he understands that his statement about love should be sincere and only Isabella is intended. He thinks what Isabella really, that she is occupied, what is close to herself - and is accepted for work
