The recent return of Prince Harry and Meghan Markle to New York City for World Mental Health Day has only fueled speculation on their intent. The couple, who were formerly in the senior royal fold, coincidentally scheduled an event on the same day as Prince William and Kate Middleton's wedding that made people question if they were trying to copy their successful counterparts' successes.

The Duke and Duchess of Sussex are very public people, always adding a paparazzi chase to their last trip in New York City. This time, they are hosting a Parents' Summit on the issue of family well-being in the digital age—very close to the heart for The Duke and Duchess of Cambridge.

Meanwhile, Prince William and Middleton hold a youth forum in Birmingham titled "Exploring Our Emotional Worlds," talking about emotional management and youth resilience—part of the mental health cause of the Sussexes.

While this parallel effort may be seen as a healthy completion accentuating shared values over royal status, others may see it as a quiet rivalry for public approval. It is not a hasty judgment since both couples have definite paths and interests.

Reports have suggested that Prince Harry could well have taken a leaf out of the book of Prince William's actions, such as their desire for a private family life and shared interests like polo, which they put in service to charitable causes. In the end, coincidentally or competitively, both couples find themselves trying to put something good back into society.
