When I came home today, Ageha was in front of my computer.
After checking history, I didn't find any particular intent behind it, as if she was just playing with a toy. However, this means she understands how to work with mechanisms, and can understand written characters to some extent.
Although she can't speak, she might be able to write. However, when I tried to give her a pen, she didn't respond.
I thought she understood what I meant, but either she doesn't want to do it, or she can't…
I have never felt hostility or malice from Ageha, so such a direct refusal surprised me.
In any case, I have no way to measure her intentions other than to keep carefully observing her.
