Little Fish Theatre is digging into the funnier side of infidelity with a Tony-Award winning play that looks at romantic plans that go awry during a disastrous family weekend.

“It’s definitely a story that is both funny and a little bit painful, because, of course, it’s so true to life,” said David Graham who is co-directing Alan Ayckbourn’s “Table Manners,” which won the 2009 Tony Award for best revival of a play as part of the trilogy “The Norman Conquests.”

The play runs in San Pedro April 22 through May 21.

It centers around Annie and her siblings: the successful and vain Ruth and the jolly brother Reg, who is married to the tough and controlling Sarah.

Annie is having an affair with her sister’s husband, Norman, a wannabe ladies man who makes a living as an assistant librarian.

The two are planning a romantic weekend getaway, but their plans are ruined when the entire family shows up for the weekend and the illicit plan is exposed.

“It leads to a lot of family, um, let’s say hilarity and turmoil,” said Graham, who as well as co-directing, also plays Reg.

The other two stories in the “The Norman Conquests” trilogy are called “Living Together” and “Round and Round the Garden.” Each story, which is a separate stand-alone play, revolves around the same characters over the course of the weekend but in different rooms in the house.

This play is the most widely produced of the three and marks the fourth production of the busy 11-play Little Fish season.

And since it can feel true to life, Don Schlossman, who plays Norman, said those who don’t see themselves in the story should probably feel a little lucky.

“I think a lot of people will be able to relate or maybe hopefully just sit back and be grateful that maybe their family might be odd but at least they’re not like that,” he said.

While Schlossman said he enjoys playing the bad boy, he considers himself among the lucky ones who doesn’t share too many traits with these characters.

“I’m a serial monogamist; I’m far more aboveboard in my personal experiences,” he assured.

Graham the director, however, was a little more mysterious when asked if he related personally in any way to this play.

“Since it involves an affair with a married person, I don’t know if I should answer that,” he said with a big laugh.
