Reading a book is different and more entertaining than reading other people prattling on. Definitely more entertaining than reading about people complaining that they're bored. And I know you're perfectly capable of reading.
It's a box and it won't shut up talks, so I think talking box is more than the right word for it.
Whoever told you it was my job to keep you from being bored? They were lying to you so you wouldn't complain about having a kid brother about, stealing all your toys.
