Flash dance

Sister of Mercy Delores Hannon, center, president of Mercy High School in Omaha, joins students in a flash mob March 22 as they dance to “Dancing Queen” by ABBA – her favorite song. Students surprised her with the action to celebrate her 50-year jubilee and as part of a school day festival capping the school’s Mission Week, March 18-22. During that week, students held numerous activities and fundraising projects, raising more than $18,000 to help displaced Syrian refugees living in camps in Lebanon. MIKE MAY/STAFF
