The letter J tends to be shy and retiring. Reluctant to jump out in the front of the titles to the stories, it tends to be jocular or judgemental. Fighting the battle of the just, it sticks like jam to its friends. It also provides justification to joking jaywalkers. It is really unfortunate that more authors do not embrace their inner J - whether that be jelly-filled or just gas.
All joking aside, the stories with titles that start with J should just be enjoyed!
