Challenge
When your fingers move like that, you know it's an omen of a challenge that will face you soon in the future.
What kind of challenge is it? If you look closely at your fingers sometimes you can figure out the challenge that is to come based on their movements.
ちょう
いど
None
In your finger, you see a challenge. And... if you look closely, you can see the fast movements of your fingers forming the outline of Mrs. Chou's (ちょう) face. Oh no, the challenge is going to be Mrs. Chou!
Whenever you see an omen (radical), there's a good chance that Mrs. Chou will be a part of it. This is not a good sign.
