My wife is a voracious reader, and I tried to get her to try e-books. That was back when it made a difference in price, but she said she wouldn’t like it. After a year of asking, she finally tried it and loved her e-book reader and takes it with her everywhere. She will still read a paperback about 2 times a year, usually if someone gives her something to read. That was over 14 years ago.
They look like Thing 1 and Thing 2 from The Cat in the Hat.
