Seyi Obakin OBE has been working with Prince William for the last 10 years. He is the man in charge of Centrepoint, who has also taught and guided Prince William about his charity work for the homeless.

According to Daily Mirror, one of the most unforgettable times Obakin spent with Prince William was when they slept on the streets for one night in 2009. Prince William apparently wanted to experience this kind of a life, even for a very short time, to have an understanding of the homeless people. 

It happened during a December night, when the temperature was unbearable.  Apparently, Prince William was struck by the knowledge that some people lived without the basic comforts of a home that many others take for granted. 

As the patron of Centrepoint, which is one of Prince William's very first patronages, the royal has been learning about this advocacy for the homeless for 15 years, first from his mother, the late Princess Diana. Obaki said that it was a great feeling to learn that Prince William wanted to work with them. 

According to Obaki, Prince William visits Centrepoint regularly, both in his private time and during public engagements. He sees thousands of people every year. 

In his private time with the homeless, people apparently open up to the Duke of Cambridge, to speak of their problems, trauma and issues. They don't do this when there are cameras and TV crews flashing their lights.

Prince William apparently motivates these young people, who come to Centerpoint for help. Obaki said that Prince William has this incredible talent of putting people at ease. He speaks to them with informality and attention that helps people open up. 

Meanwhile, the future King of England celebrated his 38th birthday on Sunday, June 21, which also happens to be Father's Day. As a tribute, the royals posted a photo of the Duke of Cambridge with his three kids, as taken by Kate Middleton, the Duchess of Cambridge. 

Prince William also had a photo with his dad, Prince Charles, the heir to the British throne. He had his arm around the heir to throne with big smiles on their faces. 

The Duke of Cambridge said that being a dad has been the "biggest life-changing moment" of his life so far. He said that he's been overwhelmed raising three kids but it's also the most wonderful experience.
