Agnes Skinner Quotes

I was in love with a soldier boy on leave from Korea. It was a fifties style of romance, five minutes of sex and a lifetime of regret. He went back to his war and I went back to my dream of pole vaulting in the Helsinki Olympics. But there was a bump in the road, a bump named Seymore.

Agnes [in flashback]

Agnes: Where did you learn to sweep like that?
Marge: I've been training all my life. I once swept red wine off a white carpet.
