Prince Charles seemingly keeps his days quite busy. Considering that the past few months have not been quite great for the British Royal Family, especially the Crown, it is only fitting why has to step up as well, like Prince William and Kate Middleton. 

Earlier this week, the Heir Apparent's office, Clarence House reportedly published a post on the royal's official social media account. It was said that the post released his very first speech about the environment. 

It is worth noting that this is one of the causes that are close to Prince Charles' heart. However, on the day of the post, several fans and netizens noticed that it was the same day as Prince Andrew's birthday.

This caused speculations to develop as no greetings were published on the accounts. Accordingly, many assumed that the Queen's first son "snub" his brother's birthday on social media.

According to Express UK, Prince Charles' official accounts on social media normally greets members of the Royal Family during their birthdays. Just earlier this year, he greeted the Duchess of Cambridge, Kate Middleton as she turned 38 on January 9. There were also four photos showing the Duchess with Queen's son and his wife, Camilla, the Duchess of Cornwall.

The same thing also happened last year with Princess Anne's birthday. It was reported that the Heir Apparent posted a photo of him and the Princess Royal laughing at each other. Along with the photo, the post greeted the Queen's only daughter for her birthday.

A few months after, the official accounts also greeted Prince George through a post. It also came with photos of the young prince taken by Kate Middleton.

This was then followed by a greeting post for the Duke of Cambridge, Prince William on June 21 as he turned 37. The accompanying photo showed the young prince as a "baby" playing with his father, Prince Charles.

With this dynamic at hand, it is not surprising why the missing greeting post for Prince Andrew has become a hot topic among reports. It was noted by the publication that no word has been heard from the Clarence House when asked about the matter.

As per Tatler, however, the Duke of York's birthday was successfully celebrated inside the Windsor's Residence, Royal Lodge. It was described as a small lunch with some of the members of the Royal Family. It remains unknown, though, if Prince Charles was in attendance.
