So basically, someone posts good news, and then the next person posts how that news can be ruined, then posts some other good news.
It goes like this
Person A: I won the lottery!
Person B: Someone stole all your winnings. I just got a new car!
Person C: It breaks down when you try to drive it. It's my birthday!
And so on and so forth.
I just learned how to skydive!
