  13. Being on an airplane with a screaming infant in your lap who has both shit on you through the diaper and thrown up curdled milk cheese on you and you've got 6 hours to go and no change of clothes and all the other passengers and crew are looking at you with either pity or scorn or both. Wait, I think that really happened. Damn.
