'a'pllying Listening should tell you it is automatiacally used
Currently when you 'a'pply the Listening skill it tells you, "For a short moment everything is silent." and makes 1 game turn pass.
This has two implications:
1) In certain situations it can be interpreted as non-sensical.
2) It gives the player an opportunity to exploit it to not, for example, stagger in a random direction while the PC is confused.
My suggestion is that it simply tells you, "You are always listening." Without a game turn passing.
