Some people think that being a royal is just sunshine and rainbows. You get to kick back and sip on some tea and maybe something stronger. While servants tend to your every need. While the royals may never have to spend a lot of time in the kitchen they actually have very busy lives.
They have to make appearances and charity events all over the world and at times they are even used as ambassadors for political reasons. The fact that only one "young" royal couple remains in the fold can change the entire way the royal family goes about things.
