When their usual skating park closes, the only place Brother and Sister can ride is a neighborhood spot where few riders wear helmets and other safety gear. It's awfully tempting to forget Mama's point: that safe is better than sorry.
Young skating fans, including those who aren't actually ready to get on a board themselves, will relate to Brother and Sister wanting to fit in and avoid bothersome helmets and padding. Parents and other caregivers will appreciate that the story has a clear message of support for Mama.
