Pants on the knees

(Picture was taken on Jan 4 and is unrelated to subject.) Dad just went to the washroom. You can tell he's done when he "clears" his nose directly into the bathroom sink making a disgusting "spraying compressed air" noise. As usual I went to remind him to flush, and saw him wiping his face with the shared hand towel again. (He always leaves booger behind. Gross!) The top of his pants was down to his knees, and legs were rolled up to his knees too. Yeah, it's like, why wear pants? I understand the top, but why roll the legs up? I wish I didn't need to see his butt. Luckily, nothing else.
