She was starting to feel really bad at the welcome wagon bit. If her Dad were still here he would be all smiles and answering their questions as best he could. She held up her phone and turned the screen toward them both. After all, it was an easier question than the 'where' and 'how' questions. "This is a communication device. It does more than that but essentially that's what it's for. If you're from after 1876 it's like a telephone, if your from before it's kind of like the telegraph, and if you're from before 1840... Well it sure beats sending a letter, or messenger." The look on mister Locke's face had said he was probably from before. "What I was doing is I was checking for messages, and checking the date. My days more or less run together so I lose track sometimes. And I turn the sound off when I'm with patients." She chuckled softly at her own expense. But she hadn't turned the sound back on, because technically she was still with patients.
Sophia was about to answer the question about what a space station was when Jacob spoke up. She gave him an apologetic look. "I'm afraid I don't know who Kant was. But a space station is basically a place for people to live among the stars. Because once you get beyond a certain point in the sky... well living creatures can't live. This basically is a giant city above a planet. If we were closer to the outer edge I could turn off the daytime 'sky' and show you, but from here it basically just look like I was a witch or something that turned from day to night." She flicked her phone so that it showed that she could turn off the day with it, as being one of the added functions besides sending someone a message.
