What is the conflict of A Marriage Proposal by Anton Chekhov?

One could argue that conflict itself is a theme in Chekhov’s one-act farce, particularly clashes between want and need, pride and humility. Take Lomov and Natalia, for example. Although Lomov goes to Natalia’s home intending to propose, from the moment he arrives, the two do nothing but bicker—first, about property ownership and later about whose hunting dog has the better pedigree. Since neither is willing to compromise, the argument escalates, causing Lomov to suffer heart palpitations. Forgetting his original intention, he leaves Natalia’s home without proposing to her.
Natalia then learns of the true purpose behind Lomov’s visit. Devastated, as she truly does wish to marry him, she orders her father to bring him back to the house. He does, but instead of a proposal, another argument about hunting dogs ensues, this time between Lomov and Natalia’s father. Although a union between Lomov and Natalia could be mutually beneficial to them, as well as collectively beneficial to their families, neither of the characters is capable of putting his or her pride aside to appreciate the larger scope of the situation. Even Lomov and Natalia's eventual betrothal fails to bring peace, understanding, and happiness: at the play’s close, all are embroiled in yet another petty dispute.
