This week’s traffic-etiquette lesson: Look, if you’re not going to use your blinkers when you’re changing lanes, could you at least signal first before shooting someone on the freeway? Thanks. FRIDAY, MAY 13 Don’t believe for one second that KathyGriffindoesn’t suffer for her art. She’s scathingly ridiculed playfully teased so many celebrities that she says she can’t even go to Fred Segal anymore for fear that she might “get attacked” by a mob of Julias and Justins. Griffin’s finally getting her own reality-TV show (on Bravo later this year), but you must see her live to appreciate how fast and feverish that gal can talk. Her new show is demurely titled ShyLady!We love you, Kathy Griffin! Please never change. At the L.A. Gay & Lesbian Center’s Renberg Theater, 1125 N. McCadden Pl., Hlywd.; Fri.-Sat., May 13-14, 8 p.m.; Sun., May 15, 7 p.m.; $25. (323) 860-7300. Remember when everyone in Silver Lake had a band? Now they’ve all got sewing machines and want to dress you. FashionRoadkill&Hello?TheEnvironmentT-ShirtConstructionNightVIis the unwieldy title of an event at Matrushka where you can choose some scraps and they’ll make you a custom T-shirt while you drink wine and wait for Spaceland to open. At Matrushka Construction, 4281 Fountain Ave., Silver Lake; 7-11 p.m. (323) 665-4513. SATURDAY, MAY 14 Though no one can afford to live there, the city of Santa Monica flaunts its virtues in your face at the annual SantaMonicaFestival.And just to rub it in even more, the lineup of music and entertainment is excellent: I See Hawks in L.A., O-Maya, Paul Livingstone & the Arohi Ensemble, plus emcee Maria Elena Fernandez. Lots of kiddie acts, art workshops, food and shopping round it out. Afterward, everyone goes home to various areas that aren’t Santa Monica and either gets depressed about where they live or lectures their friends about how they prefer their Echo Park shit-box. Clover Park, 2600 Ocean Park Blvd., Santa Monica; 11 a.m.-7 p.m.; free. (213) 365-0605.
