Bad Adults<br>Gwen and her friends were hanging out at the park. Suddenly some adults came wandering into the area. Gwen could tell they were drunk because they stumbled. Suddenly the two adults began bickering and even fighting. All of the kids felt unsafe and left the park.
Gwen and her friends didn't leave all of the kids hanging out at the park, when some rowdy, drunken adults showed up.
I guessed that the sentence construction would be too complex for the system. They didn't leave the kids, because all of them left.
