One Saturday morning Nina saw the three musketeers in the mall.
Jenny, Brittany, and Mitzi called themselves by that name because
they always were together.
"I've been shopping for sandals," Jenny told Nina. "But I have such a
wide foot nothing seems to fit. We've been looking everywhere."
"And it's been slow going," Mitzi added. "On account of Brittany's-"
"I know," Nina said looking at Brittany, "I heard you sprained your
ankle in gym yesterday. Does it still hurt a lot?"
"It's okay as long as I move really slowly," Brittany told her. "We're
going to get ice cream at the Just Desserts Shop now. Want to join
us?" "Better not,” Nina said, “ Max is meeting me at home. See you
later."

Nina was taking a short cut through Harborville's city park when she
saw Mr. Hansen kneeling beside a new sidewalk. The city
maintenance man frowned as she drew closer. "Somebody jumped
right in the middle here while the cement was still wet," he said,
pointing at two narrow footprints embedded in the concrete.
"Now I'll have to rip out this section and re-do it. Sure can't leave
the sidewalk looking like this!"
"Any idea of who did it?" Nina asked.
"A kid over there on the slide said that girls named Brittany, Mitzi,
and Jenny were the only ones near here. But he doesn't know
which one ruined my sidewalk."
"I know who did it," Nina declared.
How did Nina figure it out?
The footprints were narrow. Jenny had wide
feet. Because of her sprained ankle, Brittany
would not have jumped. Since Mitzi was the
only one left, she had to be the guilty one.
Find the 6 differences between the two pictures.
Circle Them is you know.
