I would, but I'm a cynical introvert who doesn't speak to others. Do me a favor and tell me if The Cat Returns was an actual sequel to The Whisper of the Heart.
I would, but Google know it better. Do me a favour and bring me some wood stakes with silver bullets.
I would, but I am inherently unfunny caricature of a human being. Do me a favour and supply me with more ice cream.
I would, I want to do your favour, but still you didn't tell me you wanted flavour! Do me a favour and give me your soul.
I would, but I have traded it in already and I won't get a refund. Do me a favour and change reality to a more pleasant version.
I would, but reality can be changed only to worse and horrible version. Someone call it 'upgrade'. Do me a favour and have a drink with me.
I would, but I don't believe in luck. Do me a favour and give me a better deodorant, this store-brand stuff smells like petrol.
I would but I don't think you'd want to use any of the scents I have. Do me a favour and help me figure out how to make drinks in this new glass. Last night there was too little and tonight there's (probably) too much.
