That word is
Discretion-
From dictionary.com (shout outs to the Great Keeby here

)
dis·cre·tion (d-skrshn)
n.
- The quality of being discreet; circumspection.
- Ability or power to decide responsibly.
I'll use it in a sentence: Recently, there has been a lack of discretion on the GreekChat boards.
Sorors,
I'd just like to say
thank-you for keeping it lovely on this board.
