I love you: Three words also called grunts that could cause someone to just die cause someone acted like these three words were in process. Words that are spoken too soon. Words that are not wise unless you're sure you know what you are talking about.
Good night: Words that are spoken for good dreams, love and kindness.
I will: Lies unless it is an easy task (spoken too often).
