Prince William and Kate Middleton do not rest on their duties. The couple just extended their gratitude to the teachers at a school in Burnley in Lancashire, England via video call and also encouraged the pupils whose parents work in the frontline in the efforts to stop the spread of coronavirus in the U.K. 

As Kate and William homeschool their two eldest children, Prince George and Princess Charlotte, some kids in the U.K. attend school while their parents work in frontline services such as the NHS and social care, as well as supermarkets and delivery drivers. The Duke and Duchess of Cambridge made a surprise video call to uplift the spirits of the pupils and teachers at the Casterton Primary Academy, which is located close to Burnley General Hospital. 

Though it's the Easter holidays, the school remained open so that teachers can dedicate their time to help the children of key workers. Calling from Amner Hall, the couple thanked the school staff for their dedication during the coronavirus pandemic. 

"It must be such a relief for all the parents, who are key workers, to know that the normality is there for their children - they've got the structure and they've got a safe place for them to be, so really really well done to all of you," Kate told the teachers. 

A couple of pupils told the Cambridges that their parents work for the NHS while another said his father is a packer in a bakery. William replied that both jobs are important especially this time and the children should be proud of their parents. 

The children also made a special request to the future King and Queen of England. They asked if the couple would visit their schools when the lockdown was over. Kate laughingly promised that they will. 

Another child told the Duke of Cambridge that the first king named William was William the Conqueror. Then he asked the prince about the name that he would take once he became King. Prince Charles and Princess Diana's eldest son laughingly replied that he didn't think he could answer the question. 

The children, wearing bunny ears, also showed the Cambridges their artwork from their Easter crafting activities. Some children also made portraits of their parents and explained why they were proud of them.

Meanwhile, Kate and William also talked to the School Project Manager from children's mental health charity, Place2Be, about the difficulties that the schools, teachers, and children are facing as a result of the COVID-19 pandemic. Leala Porter, Place2Be Project Manager at Pendle Primary Academy, said the call from the couple helped a lot in uplifting the spirit of the staff and the students.
