The song is a ballad, in which Ranieri attempts to write a letter to his lover ending their relationship. He repeats the phrase "You said that the one that can tear us apart will never be born" and also tells her that "life is a storm, stronger than us" in his attempts to rationalise the breakup. It appears that he is as despondent about the end of the relationship as he believes she will be, but no reason for it is offered.
Also, this was the first year that the ESC decided to have preview videos promoting the songs competing in the contest. Apparently, Massimo's video was filmed in color, but the location of the shoot is pretty sketchy, since the Italian TV network, RAI didn't convert to color TV until 1977. Plus Massimo's appearance looks a lot different from his appearance at the ESC. Apparently the song and preview video were both recorded in 1970. In the video, he demonstrates all of his emotions in the song very well.
In conclusion, it was rumored that he was favored to win the contest, since he was asked to record the song in Spanish, French, German and English. However, only the French and Spanish versions have been heard.
