Accidents happen. But some accidents are a lot worse than the others. In some accidents nobody dies, in some accidents one person dies, but in some, a number of innocent lives are lost because of one person’s ignorance. You leave your house, leaving behind people who are expecting you to be back home, but you don’t. Isn’t it too tragic?
Sometimes accidents happen because of people’s own folly. They drive carelessly, they drive while they are drunk, they don’t follow the traffic rules and whatnot. But sometimes it is sheer bad luck. Accidents happen when they are least expecting it.
