I do not even know you, therefore, why would I respond to humor with you? Chupa me pito. Or perhaps in another language, va te faire voir. And when you finally learn the translation of those, feel free to find me. Just because I am not smiling all the time or in a pleasant demeanor does not mean you have the right to take it upon yourself to, as you put it, lighten the mood. I was in the middle of studying. There was no mood for you to barge in on. And finally, at least even though I seem to speak as if reciting, I can get laid, let along keep a relationship.
