Doubt? ASK ME

CHUBUKOV: Oh, don’t go round and round it, darling! Spit it out! Well?
LOMOV: One moment... this very minute. The fact is I’ve come to ask the hand of your daughter, Natalya Stepanovna, in marriage.
CHUBUKOV: [joyfully] By Jove! Ivan Vassilevitch! Say it again — I didn’t hear it all!
LOMOV: I have the honour to ask...
CHUBUKOV: [interrupting] My dear fellow... I’m so glad, and so on... Yes, indeed, and all that sort of thing. [Embraces and kisses Lomov] I’ve been hoping for it for a long time. It’s been my continual desire. [Sheds a tear] And I’ve always loved you, my angel, as if you were my own son. May God give you both — His help and His love and so on, and so much hope... What am I behaving in this idiotic way for? I’m off my balance with joy, absolutely off my balance! Oh, with all my soul... I’ll go and call Natasha, and all that.
After some time, Lomov revealed that his true motivation for coming was to ask for his daughter's hand in marriage. Chubukov was extremely happy to hear that Lomov had come with a marriage proposal. He asked Lomov to repeat what he had said because, in his excitement, he could not believe what he had just heard.

Chubukov showed his happiness and satisfaction with great joy. He struggled for words to convey his joy. He kissed Lomov, overcome with emotion at watching his long-awaited desire come true, saying Chubukov always loved Lomov as if he was his son. Lomov's proposal for his daughter made Chubukov cry joyfully. He then realised that he was behaving so idiotically. But, before Chubukov realised what he was doing, he gave his blessing to Natasha, his daughter, and Lomov. Then, he left the place, saying he would call his daughter Natasha.
