So here's the context. Madhav stared at the girl driving beside him, not for the first time. She was probably about his age, with dark brown hair cut pretty short, up to her shoulders. “Again, I can’t thank you enough for this. Thank you so much.” She looked at him, and smiled. The smile seemed to light up her already pretty face. There was a twinkle in her eye, and for some reason, Madhav got the feeling that that twinkle was always there. “I already told you, I’m going the same way. There’s no need to thank me as profusely as all that.” With a start, she jerked her eyes back on to the road and sighed. She was obviously a very bad driver. “So. What do you think happened to your car?” she said, her eyes still on the road. “Don’t know. Something to do with the radiator fan, or the break fluid, or the carburetor, I suppose. Or maybe the gear transmission is messed up. I have no idea. That car is almost six years old. That’s menopause in cars, no? For all I know, there may be a giraffe peeing into the fuel tank.” She laughed. “I see. You obviously know a lot about cars.” “Careful with your sarcasm. It’s dripping on me a little.” She laughed a little harder that time. She liked that, did she? He could come to love this girl. He shook his head in *blank*. I can't, for the life of me, think of a word to fit. Any ideas? I'm looking for something that will explain a cynical attitude towards his own thoughts, a slight sense of self-pity, and amusement. I know this is really desperate, but I am, for the lack of a better word, desperate. Thank you!
