"Yes, it's ending..." Su Zhan sighed lightly. "The days with Argon II are coming to a close! It's a bit hard to let go when you think about it. I've spent two or three decades with this thing right from the start. How do the ancient sayings go... This is youth!"
"'Youth'? What's that?"
"Hmm, it's a shared cultural experience of physiological age fourteen to twenty-four?"
"What's that?"
"Anyway, it's just an adjective," Su Zhan waved his hand, then remembered the puzzling question he had.

But in the direction it has chosen, there isn't a substantial destination within those dozens of light-years." Su Zhan took a sip of wine, "Am I being presumptuous if I write 'Argon II is probably heading towards the Solar System'?"
