Hearing Distance

I trotted down the rough wooden stairs after Chapman. Very weird, by the way. Going downstairs as a cat gave me a feeling of vertigo. I mean, I was going down head first. It's strange.

<Look, Tobias, I appreciate you looking out for me. But I'm kind of busy right now.>

<I understand. I can't hear you very well, anyway. You're getting farther away. >

<Yeah, I'm going down.> I waited. He said nothing. <Tobias?> I called. But there was no answer. We're still learning about thought-speech. We know there are limits on how far it can be "heard." But we aren't sure what the limits are.
