Overseas flight from Brussels to Chicago. After lunch was served, time for “lights out” so we can sleep to help get back on USA central time, 7 hours behind. Guy behind me in Polaris was apparently very entertained by whatever he was watching and would burst out loudly laughing. Of course, this happened just as I was falling asleep. I wish flight attendants would have asked him to keep it down. Also, it would be great if flight attendants weren’t banging around things in the galley, or do as little as possible, banging around. The food was surprisingly good, and I loved the return of the ice cream cart! I looked at the offerings of movies and TV shows and nothing looked good to me. I just tried to sleep. I don’t feel like I got much sleep, though.
