People may forget what you said, but they'll never forget how you made them feel. I find that my memory does hang on to some things, which, honestly, i find to be not that useful. Mostly i remember, though, how i felt. I remember whether i liked it or whether i didn't like it. Maybe that's what i want to remember. It could just be functional. So if you're reading for pleasure, i don't think the intent is to remember the plot, the characters and so on,. because you're in the moment when you're reading. What a waste of time. There is nothing there. You read before bed every night, i do.
