Well, for one thing I'd not have been able to read your pamphlet right away. Your letters are different to ours.
Things I wish I'd been told straight away? That I'd gone between worlds. That would have been right helpful to know and saved a lot of confusion. That you can't trust people here. That people here have no proper sense of loyalty. About the cars. That's important. And how the machines in the apartments work, although that I figured out on my own in the end.
