Boston-area parenting expert Joani Geltman , who just released the book “A Survival Guide to Parenting Teens: Talking to Your Kids About Sexting, Drinking, Drugs, and Other Things That Freak You Out,” had a special guest at her Porter Square Books reading on Monday — her daughter, actress Ari Graynor, star of the new CBS comedy “Bad Teacher.” Graynor introduced Geltman, who then shared parenting tips and took questions from the audience about today’s tech-savvy adolescents. Graynor, who wrote the book’s intro, said she’d be running back to New York City to prep for her upcoming run in Second Stage Theatre’s production of “American Hero” with Jerry O’Connell.
