Reason for a tucked tail, perhaps

GUILT

Think of the heavy feeling after doing something wrong—it might make you avoid eye contact or shrink away.

A tucked tail in animals often signals fear or shame, which ties to the human emotion of guilt. The clue plays on that natural behavior to hint at the answer, using "perhaps" to suggest it’s not literal but a metaphorical connection. It’s a straightforward definition clue with no hidden wordplay—just a relatable observation about body language and emotion.
