No PDA
Because they were at work, Prince William and Kate did not appear to be very affectionate in the eyes of the public. We knew that touching hands or giving hugs while on the job was improper. That is another reason the royal couple would not have shown their unwavering affection in front of the general public or the media. They were both aware of their obligations and duties as monarchies.
Official Photos
The Duke and Duchess are almost always captured in photographs taken during official engagements, so it would be unprofessional for them to hold hands, according to Emily Nash of Hello in the interview from 2017. She continued, “They also need to shake hands with a huge number of people as they meet them, so aside from being on duty, it wouldn’t be convenient! She went on to explain why the royal couple would not publicly show their affection for one another.
