Prince William is speaking from the heart. The Duke of Cambridge and his wife, Kate Middleton, attended the opening of the Manchester Arena memorial, which is a tribute to the 22 people who died after a bombing at the Ariana Grande concert in 2017. During his speech, Prince William opened up about his own experience with grief, which he went through firsthand when his mother died in car crash in 1997 when he was 15 years old. Source
