No, your ears are not playing tricks on you. My 89-year-old grandmother, who just had to get a breast removed due to breast cancer, who survived the bombings in England during World War II, who looks really old fashioned...actually said she wants to read a manga. She thinks it looks interesting.
I gave in and lent her my (now broken!) copy of Udon Entertainment's Les Miserables manga...though the entire front and back cover peeled right off for some reason (it was paperback). I MUST encourage this! If she ever comes to visit my house, I am taking her to my room and we are gonna have a manga reading party so I can show her all my favorites! She likes reading and reads fast like I do, so it'll be absolutely perfect!
I am so giddy about this it's not even funny.
