Halycon's guide to identifying Mono no Aware in Anime:
Every time the camera focuses on a petal/leaf/waterdrop/snowflake/bird/fish in motion, that's mono no aware.
Every time the camera pans from the sky/moon/space to show a village/valley/ruins/city/our heroes or vice versa, that's mono no aware
Every time someone throws out a deep and profound one liner on the state of the world/the hero/the scenery/life/poetry, that's mono no aware.
Every time the main lovebirds slowly turn their heads to look at each other, before turning them back and looking out over the horizon, preferably at a sunset/sunrise, that's mono no aware.
