The question any novel is really trying to answer is, Is life worth living? That's a major question, a huge question, but the best way to answerit might not be to crank the novelistic universe into a crude, lurching motion by employing a big inciting incident. Sometimes life provides only the tiniest of telling incidents--that your left shoelace snaps within a day of your right one. That's enough for me. When something is beautiful, it can't be minor.
I kind of get that-- we don't always know what the meaning is that this event or moment will convey, but if it's amazing, the reader will find the meaning.
