Fortunately is the title of a book by Remy Charlip. Basically, it follows a day of the ups, down, narrow escapes and unlikely triumphs of the protagonist. Perhaps you remember it? If so, you have probably noticed the same sine wave making itself known in all parts of your life. It’s supposed to start with “fortunately,” but for example:
Unfortunately, Jacquie cracked the screen on her cell phone.
Fortunately, replacement screens are readily available.
Unfortunately, I only ordered the LCD, when I needed the glass as well.
Fortunately, those are available too.
Unfortunately, I already have the phone disassembled:
Fortunately, I have spare, unlocked phone available.
And so on …
