This face represents the feeling of ehness. Or just eh.

Hard one to define imo.. I guess it's
1. This sucks.
2. Whatever
3. Greeeeeeeat (sarcasticly)

1) An agreeable response to a problematic situation in which the situation is out of the control of the responder or both parties.

-or-

2) A somewhat regretful, conflicted response to a decision already made or one that is currently being made by the responder.

The act of being:

1) Unsure
2) Sarcasm
3) "Yeah sure."

The face you use when you don't know what to say.

1. the smiley for being unsure and sad.

1. Indifference or 'meh' is the best i can think of :/
