You feel very strange talking to a piece of paper but you decide to find out more.
"What are you," you ask the bookmark.
The words fade complete out and the reappear:
"Call me Mark"
"Mark huh? Well I'm Wilson"
"That I know"
Strangely enough, you begin to feel more comfortable talking to this piece of paper now that you know it has a name.
"Mark, how can you talk... I mean, what are you?"
Mark's readout quicxkly fades to nothing then reappears:
"I can display"
Before you can ask what that means each letter begins to spin eventually stopping and forming a new sentence.
"only three words"
These words begin to fall being quickly replaced by new ones.
"at a time."
Ah... you understand... Mark can only show three words at a time. That's why all of his answers have been three words long.
You decide to ask questions that only require a few words in reply.
You say, "Ok, I understand. Let me ask this: Are you a person... I mean are you alive?"
"Yes I'm alive."
"Where are you from?"
"Can't say now."
"You can't say now? Why not?"
"Open the book"
