Fortunately/Unfortunately

[wild rose]

Unfortunately, someone accidently spills a pitcher of water all over your work an it gets soaked and ruined

[stargazer]

Fortunately, the person who gave you the paperwork was very thorough, so you have backup copies of everything.

[The Rose-Tree Dryad]

Unfortunately, by the time you're able to mail the paperwork, it's already too late and they've set a band of raging animal rights bandits to come collect you.

[Ryadian]

Fortunately, your lawyer appears with proof that the elephant was, in fact, imported legally, so all this hassle was totally unnecessary.

[The Rose-Tree Dryad]

Unfortunately, your lawyer has been disbarred from practicing law and can't help you.

[Ryadian]

Fortunately, something else has come up, so now the Royal Society is distracted and forgets about you.

[The Rose-Tree Dryad]

Unfortunately, the raging animal rights bandits haven't yet got the memo and are still coming to get you.

[Meltintalle]

Fortunately, you're getting very practiced at evading hunters and you take a vacation in the Sierra Nevadas.

[waggawerewolf27]

Fortunately it is snowing in the Sierra Nevadas and so any remaining hunters get bogged down in a snow-drift.

[stargazer]

Unfortunately you weren't prepared for that snow and now you're shivering in a cave.

[waggawerewolf27]

Fortunately it is warmer as you go further in the cave, and you always carry a torch with you as you wonder at the stalactites & stalagmites.

[Quinlin]

Unfortunately, your torch blows out with a sudden gust of wind and not seeing the path before you, you plummet into a giant pit.

[stargazer]

Fortunately, you land on something big and soft and aren't injured from the fall.

[aileth]

Unfortunately, it is a very angry bear.

[Meltintalle]

Fortunately, it was hibernating and so you can scramble into a crawl space and listen to it growl about people not looking where they were going.

[waggawerewolf27]

Unfortunately, the bear sinks back into a deep slumber and the radiated warmth of its body lulls you into a much needed sleep as well, before you can escape.
