I have a definition of Hell. It’s a sort of Flying Dutchman thing. It would be a flight from Boston to Glasgow that never touches down. The ingredients would be first of all the addition several extra rows of seats on the plane. This ensures that if the person directly in front of you reclines their seat it rests against your forehead. Then don’t upgrade the air circulation system to cope with all the extra passengers crammed into the Smartie Tube with Wings thanks to the added seating. Make it as stuffy as possible.  But here’s the kicker. Offer free booze to the passengers as compensation for something. This will ensure that many of the male adult passengers become pissed and obnoxious. And that their wives and girlfriends start nagging and rowing with them.  And there you’ve for your recipe for a Living Hell.
