Princess Diana tried to give Prince William a normal childhood experience, but apparently there are some things that just couldn’t be taught within the palace walls in the 1980s. He may be remarkably down-to-earth now, but there was once a time that a grocery store run was an overwhelming experience. Unsurprisingly, the key figures that brought the Prince of Wales into the normal 21st century were his very normal parents-in-law during the early days of his relationship with Princess Kate.
