Instead of FOMO. Fear of missing out. It’s FOROOB Fear of running out of books!
I must admit, i have it too and brought 7 books with me on my first cruise. When I switched to Kindle, I had a panic attack at 2am, in the hotel the day of the cruise. Woke out of a dead sleep thinking I forgot my kindle. I had to get out of bed, rummage through all of the bags to make sure it was there. IT WAS!!!!
