Mr. Salt: Ladies first, and that means Veruca.
Grandpa Joe: [to Charlie] If she’s a lady, I’m a Vermicious Knid.

— Willy Wonka and the Chocolate Factory

If you want to be treated like a lady, act like one.  I’m not saying you should act like a shrinking violet. A woman can be a beer drinking hell raiser, and still deserve to be treated like a lady.  What makes a lady is what makes a gentleman: honor.  A lady doesn’t lie, steal, or cheat, nor does she tolerate those who do.  She stands up for those who cannot, defends that which is right, and never turns away from a challenge.
