He says, “Thank you. I’m happy that you were born as my child. Thank you for being my son.”
She says, “Thank you.” He is not sure how many times he heard the word from her. He is not doing it just to hear her saying thank you. He probably want something more than just that. And that is why he is sticking to her trying to do anything for her. Her appreciation with smile do not satisfy him anymore. He has done more and more meaningful things he can help her. He used to say, “You’re welcome,” but he doesn’t even reply to her anymore. His mind is in chaos that he can’t get out of.
He thinks, ‘The one who loves lose. What can I do? I guess I should be more sincere and loyal until she loves me back.’
He comes out of building through the door. She is coming from distance to the door. He holds it for her, not fully caring and looking where she is. She lightly hastens her walking to the door. She says, “Thank you,” with a smile on her face. He glimpses at her with a hardly visible grin, and replies in hardly audible voice, “You’re welcome.”
