DD started Yr7 3 weeks ago. Once a week she goes by bike as she doesn't have time to come back at lunch before going to her sports club. It's getting dark in the mornings when she leaves now. She's still wearing children's sizes so her coat has reflective strips on it, but these are covered by her sports backpack, which is bright blue with a black base. When she's on her bike, all you see is the black base. WIBU to cut a couple of strips of reflective tape to stick across the base of the bag so she's more visible?
Her bike is kitted out properly with lights/ pedal reflectors and once it gets colder and she starts wearing trousers to school, she's got some reflective bands for her ankles.
YABU - no, don't do it, you'll embarrass the poor child!
YANBU - yes, it's the sensible thing to do.
