When Worlds Collide

As you push open the door of the sweet shop, the cashier looks up at you and smiles. You smile warmly at the old lady, who only smiles broader, then goes back to sorting assorted candies. As you browse along the aisles of the quant shop, you can't seem to chose a candy. There seems to be an endless amount of possibilities. Each candy calls your name, begging to be chosen and cherished. You end up buying an assorted basket of candy, and the lady thanks you, smiling at the obvious excitement on your face.
