->'''Reggie:''' What did you do?\\
'''Joy:''' I made blueberry pancakes.\\
'''Reggie:''' You make those when you feel guilty.
-->-- ''Series/DeadLikeMe''

Alice knows Bob very well. She can always tell what he's feeling. She'll probably say something like:

* "You always clean when you're angry."
* "You're only nice to me when something is wrong."
* "Whenever you have a bad day at work, your foot shakes."

The idea is that Alice can tell something about Bob's emotional state because he is performing a significant but unrelated action. Expect Bob to deny it. Don't expect to ever see him perform this action again, even though he supposedly does it all the time.

Writers will often use TheTell to inform the audience what is going on with a character who wouldn't normally share his feelings.

See also YouCanAlwaysTellALiar and PinocchioNose for cases where Alice can tell that Bob is lying. See TheMagicPokerEquation for {{poker}} tells.

[[folder: Video Games ]]

* This is a game mechanic in ''VisualNovel/ApolloJusticeAceAttorney''- when a witness is nervous while testifying they'll perform some sort of habitual action that you have to zoom in on and then call them out on.
* Also a benefit of the advanced facial animation technology present in ''VideoGame/LANoire'', where during interrogations, a suspect may have a telling reaction as they wait your response to their testimony and you must gauge the correct response based on that. Some [[http://www.youtube.com/watch?v=IvtMZ20DmJo more telling than others.]]
** Also subverted in that a tell is not a sign of lying, and a lack of tell is not a sign of telling the truth.
