'I kept this up for the 4 hour flight': Passenger gets even after entitled seatmate takes up too much space on flight

Who you end up sitting next to on a plane while traveling solo is truly a game of luck. Sometimes, you'll board the plane and the seat next to you will remain empty for 90% of the boarding process until some random annoying dude who was running late makes it onto the plane at the last minute. Other times, you're seated next to a screaming child who is on his very first flight.
