In the first episode of the new season, Meredith Goldstein asks: Whatever happened to the good old-fashioned set-up? She talks to two friends with starkly different views on whether set-ups are worthwhile, and she visits a salon that offers far more than haircuts. Plus, Meredith introduces Erin, a 44-year-old single woman whose dating life Love Letters will be chronicling all season. Email us at loveletters@boston.com.
