Yar, welcome to Fortunate, Unfortunate. 'Tis a simple game to play, for example:
One person would say something like, "Fortunately, I have a dog."
The next poster would say, "Unfortunately, it ran away."
And so on. You'd continue with another "fortunate", being followed by yet another "unfortunate".
I'll start us off.
"Fortunately, I can ride a horse."
