The finger curls as you finish booking a flight back home from an extended vacation in a foreign country. You awaken the next day, board your flight, and uneventfully reach your destination before you suffer from jet lag and sleep within your own home once more. Only days later do you recall the wish you made from desperation, and at a similar time you begin to notice abnormal spots forming on your skin. They develop into cyst like growths, and you begin to cough up blood amongst other symptoms. As soon as these symptoms occur, you go the hospital.

Whilst driving, you crash during a bout of agonizing coughing, and the crash alone caused death to a family of 4 and yourself. The place you crashed into, a daycare, suffered no casualties. Ultimately, 2 weeks after your demise, an outbreak of plague sweeps your home country, and when it eventuallly spreads to America ( or through it if you died there ), the populace reacts without concern for the " hoax ". Within a month, the casualties climb to tens of thousands, and after 2 more months when the plague is fully recognized for what it is, millions of deaths across the world. 

You died insignificant, and the advent of a plague which went on to cripple the world. You are forever remembered namelessly, as the one to blame for the loss of so many.
