Argentinian playwright Ricardo Talesnik is a master of farce, as his “Las Quiero a las Dos” (“I Want Them Both”) at Teatro de la Luna makes clear. A play about the roles people play in life and how well they do or don’t adapt to the parts they have created for themselves, “Las Quiero a las Dos” is the story of a businessman, Miguel (Peter Pereyra) who is married to Julia (Yovinca Arredondo Justiniano).
