Juliette (Me) As A Character

Today (well, okay, yesterday) in English class we were learning about facts and opinions, and the difference between them. Then we had to fill in an opinion sheet called "The Best", where it would say "The best [something] is..." and you had to fill in the blank with what you think is the best color/tv show/food/other is. When we were done, we shared ours with the rest of the class. One boy, Max, decided to share his...
Max: The best teacher is...Mrs.Short-Robertson!
Mrs.Short Robertson: [laughing] Oh, suck up.
Max: I said it was an opinion, not a fact.
