Both touching and hysterical, the sentimental comedy Triangles returns to the Pocket Sandwich Theatre more than 30 years after it was first performed, still packing the same emotional wallop. Written by Pocket co-founder Joe Dickinson, the play contains three one-act explorations of relationships. In Act I, a woman turns the tables on her errant husband with unwitting help from his best friend. In Act II, a young couple comes home to ask permission to marry, which leads to its own complications. And in the final act, two old friends still bicker about past loves and future adventures.
