The most hilarious part of "mute as a fish" verb is that fish are one of the creatures that tend to chatter ALL THE TIME. Like, chirping, honking, oinking, snoring or just plain screeching. Sometimes they also snort and growl. (not buble) Coral reefs are like spring forests where your ears are chattered off by bunch of angry compretitive songbirds. Okay. Ocean, the Voidy domain... It's like seeing into blackout or Furthest Ring, thinking that it's empty and quet when it's just you missing talks.
Is… Mute as a Fish something people say? Remember, not natively English here.
