It would have been hard to deny that Acha was frightened. She recalled that Amy had said to simply not open the door; and though she had to trust Amy's judgment, it was still hard to not think of the fact that someone was at the door and wanting to come in. She froze so as to make no noise at all, and very slowly, very carefully reached out with her mind to look. She had only seen two humans before, Any and the man who had brought the samples; this person was neither, but there was some similarity and she assumed it was a human. But she didn't dare look too closely. What if the visitor notices she is looking? Her people could, of course, but then their mind was equipped for that, and, as far as she knew, humans weren't usually telepathic. Still, she only stole a glance and withdrew. The person didn't seem hostile. That made her relax some. If nobody opens the door, the visitor will surely leave soon. Nonetheless, she looked around for a hiding place, just to feel safer. Under the table? No, he will immediately see her. Maybe inside the wardrobe? That's it. Now only to get there as quietly as she can... She wished Amy was home already.
