You can pick your friends and you can pick your nose, but you can't pick your family. If you could, there'd probably be a lot less tension in the Cheney family. We're sure Dick Cheney loves his lesbian daughter Mary, but she hasn't exactly simplified his campaign. Likewise, Mary's support for her old dad has led to scrutiny about her loyalty to gay rights issues. Check out a similar, but fictional, situation when Fort Worth's Q Cinema hosts a screening of Poster Boy, a festival-circuit film about the closeted gay son of a right-wing politician whose homosexuality is used by an ex-lover to disrupt the campaign. The screening is at 8 p.m. at the Four Day Weekend Theater, 312 Houston St., Fort Worth. Admission is $5 to $7, which includes an after-party at Club Vivid. Visit www.qcinema.org.
