Fortunately/Unfortunately

[Damon Wecks]

First person says something unfortunate that happened, next person turns it around to a good thing. 
Ex. 
Unfortunately, I can't get on that much tomorrow. 

Fortunately, I'm going canoeing instead. 

Unfortunately, the water I'm going canoeing on is really dirty. 

And so on and so on. 
First one: 
Unfortunately, I almost barfed of dehydration today.

Fortunately you get special treatment for the next week
Unfortunately it seems like I'm going to fail my summer course

[Damon Wecks]

Sorry if I didn't make myself clear, but you only say one thing, either an unfortunately or a fortunately. Also, they're supposed to be related. Again, sorry I didn't make it that clear.

Fortunately, I have a chance to retake them
