Coffee
So, yeah, you loved your cup of coffee with the usual two teaspoons of sugar. But then one day, someone came along and made it your cup of sugar with two teaspoons of coffee in it. And you loved it. And you loved that someone. But then one day, when it was over, you hated it. And you hated that someone. Because your cup of coffee with the usual two teaspoons of sugar would never taste the same. And all you'd taste then, would be the coffee. The bitter, bitter coffee.
