Answer:
When Vivien talks of crying, she meant to say that she will manipulate Lancelot into marrying her and not going away from the village without her.
Step-by-step explanation:
"King Arthur's Socks: A Comedy in One Act" by Floyd Dell is a satirized modern version of the legend of Lancelot of King Arthur tales. In the play, Vivien reveals to Guenevere Robinson about her love fro Lancelot who happens to also love her in return but wants to concentrate more on his career and not marry her. She fears that he will leave her alone and she will never see him again. When she says that "there's lots of things I can do. Cry, for instance", she is implying that she intents to manipulate Lancelot in giving into him when he sees her crying in front of him. Women have always employed their crying as a way of manipulating their men, prompting them to relent and this is exactly what Vivien intends to do.
