Before all cultural information was transmitted via MTV and gangsta rappers, children and adults in the ’40s and ’50s were forced to sit attentively and watch films explaining in precise detail how they were to behave and what society expected of them. If they didn’t, it was noted on their permanent record. When you view these two evenings of educational and industrial shorts—and attendance is mandatory—I suggest you pay close attention. “A More Perfect You” on Friday, features Shy Guy, Good Grooming for Girls, Office Courtesy, and The Other Fellow’s Feelings; Saturday’s program, “Outdoor Romances,” includes Are You Popular?, Date Etiquette, Are You Ready for Marriage?, and More Dates for Kay. At 8:30 p.m. at the Lubber Run Amphitheater, N. 2nd & Columbus Sts., Arlington. FREE. (703) 358-6960. (Dave Nuttycombe)
