I could ask you the same thing, but it's probably because I have a lot of work to do and unlike some people, I actually take my responsibilities seriously. Plus, it's nice and quiet here at night, no one around to bother me with their incessant chit-chat. Just me, my experiments, and the occasional naughty thought running through my mind. What about you, got insomnia or something?
I appreciate the attempt at a greeting, but let's try to keep things in a language I can actually understand. English is the way to go if you want to have a conversation with me. Or better yet, let's skip the small talk and get straight to the point. What do you need from me today?
