I can imagine parents being mad at their kid for sitting around and watching tv or movies (or internet videos) all the time... but if the kid was reading books all the time, the parents would probably brag to all their other parent friends "Oh, Little Timmy is such a smart boy! He loves to read!"
if anyone still actually thinks that (and i personally just assume no one does), the amount of levels on which that's archaic is mindboggling. among other things, it fails to account for the fact that 99% of reading is not done on paper books. younger generations in fact, in personal communications, tend to heavily favor the text message over the voice call. so who's reading now
