President Donald Trump will meet Queen Elizabeth II for tea in London on Friday, July 13.

According to TIME, Trump needs to remember certain rules when it comes to meeting the Queen. For instance, the president of the United States is not allowed to be too affectionate. He should not also expect to be hugged or kissed by the 92-year-old monarch.

During their upcoming meeting, Trump should not extend his hand to shake the Queen’s unless she’s the one who does it first. If they have the opportunity to shake hands, they should do so briefly. Trump should not also converse with the Queen for very long periods of time.

The president should address the Queen as Her Majesty during their first meeting, and he should call her ma’am throughout the rest of their time together. He should not also turn his back towards the Queen or take photos of her without her knowledge.

Trump and his wife, Melania Trump, are not expected to bow or curtsy to the Queen, according to Hugo Vickers, a book author and expert on British royals.

“That wouldn’t be required from a head of state or the wife of a head of state. He would be wise not to attempt to kiss her, and I don’t expect for a moment that he will,” he said.

During a recent interview, Trump said that he’s not nervous to meet the Queen. He also dubbed Her Majesty as a tremendous woman.

“I really look forward to meeting her. I think she represents her country so well,” he said.

Meanwhile, Vickers also shared some predictions regarding the president and Queen’s upcoming meeting. He said that the monarch will most likely have an impression of Trump, but she won’t talk about it publicly.

“Whatever we think of President Trump, he is the elected president of the United States of America and he has been invited to this country and he must be treated with great civility. The Queen will obviously be very courteous to him,” he said.

Regardless of what will happen on Friday, Vickers and TIME believe that the Queen will keep her composure no matter what.
