You’re correct. He shares a hospital room with Billy Pilgrim. Rosewater was there for alcoholism treatment. Eliot coaxes Billy back from his silence by talking about Kilgore Trout’s science fiction stories. Eliot had a tremendous stack of Trout’s books under his bed and let’s Billy read all he wants. Of course this turns Billy into a big fan or Trout. Vonnegut is quite an artist.
Price trackers help, but I noticed the past few years they have a trick that price trackers don't account for. Coupons. Before prime day, they have an inflated price, but a near permanent coupon (those where you check a box and get a discount) Price trackers see the pre-coupon price. and don't account for the coupon. When they want amazon and the price tracker to show a deal, they remove the coupon and lower the price.
