So basically all you've got to do is:
1.) Someone will start of with an Unfortunately phrase/sentence/etc.
2.) Someone replies with a Fortunately phrase/sentence/etc.
3.) And then the next one would be Unfortunately and etc....
e.g
Person 1: Unfortunately I ran into a goat.
Person 2: Fortunately, the goat gave you milk.
Person 3: Unfortunately the milk was poisoned.
and it goes on...
