Okay so, this is kind of hard to explain…
Someone will start a scenario with "Unfortunately". Something that is negative, you know like bad news about life, or something. And then you will counter it with "Fortunately". Something that is positive and makes the negative seem better. But it has to relate to the post above you.
EX. (I'm terrible at examples…)
UNFORTUNATELY your dog died from aids
FORTUNATELY you have 5 more dogs
~
UNFORTUNATELY having more than 1 dog is now outlawed
FORTUNATELY you can have as many cats as you want!
Think of it as like one word story time or whatever. Just keep the fortunes going!
