Stare
When your eye catches an omen, it's only natural that you will stare at it.
You don't see omens that often, so of course you're going to stare. We'll imagine what the omen is in the reading mnemonic.
ちょう
なが
None
As you stare at the omen, you see Mrs. Chou (ちょう) knocking down buildings, putting nails on the street, and making herself way longer than you ever thought possible. Oh, and there she is, destroying the world.
Whenever you see an omen (radical), remember that the omen will probably have Mrs. Chou in it!
