The royal couple went to Luton, in the north of London, where they visited charities that support young people and talked about mental health and emotional wellbeing.
During a visit to Youthscape on Wednesday, August 24, William joined several teenagers who were playing a computer game and talked to the youngsters about how the organization can help them cope in difficult times.
The Prince also took time to comfort an orphan who lost his mother to cancer last year and gave him advice based on his own experience.
“Time makes it easier,” he told 14-year-old Ben Hines. “I know how you feel. I still miss my mother every day – and it’s 20 years after she died.”
“The important thing is to talk about it as a family. It’s OK to feel sad, it’s OK for you to miss her,” he added.

The Duke also asked the boy, his brothers and their father to keep talking to each other.
“As four boys, you have to talk a lot better – we’re not good sharers. It’s a classic example of lots of talking needed,” he said.
William was 15 when Princess Diana died in 1997 in a car crash in Paris.
