What are some quotes from August: Osage County?

August: Osage County is a play by Tracy Letts. The action is centered on an extremely dysfunctional family with a patriarch who has disappeared and is later discovered to have drowned himself. We see a wide range of problems in the Westons' lives, including affairs, incest, and addiction. Needless to say, tensions run pretty high throughout the story, so there are some great quotes to choose from.
Here's one from Beverly, in his interview with Johnna at the beginning of the play:

My wife takes pills and I drink. That's the bargain we've struck . . . one of the bargains, just one paragraph of our marriage contract . . . cruel covenant. She takes pills and I drink.

I think this gives you a pretty good sense of how well the couple was doing in terms of sobriety. 
Here's another from Beverly's eldest daughter, Barbara, whose marriage is falling apart:

Thank God we can't tell the future. We'd never get out of bed.

Pretty bleak, but Barbara doesn't have much good going on in her life at the moment.
From sisters Ivy and Karen:

Ivy: This isn’t whimsy. This isn’t fleeting. This is unlike anything I’ve ever felt, for anybody. Charles and I have something rare, and extraordinary, something very few people ever have.
Karen: Which is what?
Ivy: Understanding.

This chunk of dialogue isn't as heartwarming when you find out that Charles and Ivy are actually brother and sister, a fact that's been hidden from them both their whole lives. 
And here's an exchange between Barbara and Johnna: 

Barbara: Johnna . . . what did my father say to you? (Pause.)
Johnna: He talked a lot about his daughters . . . his three daughters, and his granddaughter. That was his joy.
Barbara: Thank you. That makes me feel better. Knowing that you can lie.

There are many, many more quotable moments in August: Osage County, but these few should give you a good start!
