Taken from Fun and Games group in GR.
Person 1 posts a sentence, and the next person has to develop this sentence - but using Fortunately/Unfortunately at the beginning of every new sentence.
You can choose what to use - Fortunately/Unfortunately - as you wish
Person 1: I went to a bookstore today
Person 2: Fortunately, there were lots of new books in there!
Person 3: Unfortunately, all of them belonged in a genre I hate
Person 4: Unfortunately, although I was open for new reading opportunities - they were all pretty cheesy
Person 5: Fortunately, I've just finished a lengthy, high-level classic piece of literature, I needed something light and stupid to balance it
Person 6: Fortunately, I saw all of them were on sale! 60% off, wow!
Person 7: Fortunately, I quickly found a book I might love so I bought it right away
Person 8: Unfortunately, my teacher just saw me holding my brand new copy of "teenage love" and gave me this weird look. Awkward!
and so on. Fun, right?
