Write a short answer with a quote saying. What incident was major turning point in montages life and why ?

The turning point in Montag's life would be when he meets Clarisse. For the first time a light goes off in his head when he realizes that he's not happy. Even more than this, he begins to consider just how much society is ignorant and void of meaning,

"You're not like the others. I've seen a few; I know. When I talk, you look at me. When I said something about the moon, you looked at the moon, last night. The others would never do that....are you happy?" (Clarisse)
