According to royal etiquette, ladies must curtsy and gentlemen must bow from the neck when they see royalty for the first time in any given day.
So, when William and Catherine are staying with Queen Elizabeth and seeing her every day, each day they must show their respect in this way. We are assuming that Princess Beatrice had already seen her grandmother, the Queen, on Easter Sunday and so had already shown her the proper respect.
Apparently, the longer one pauses in the curtsey, the more respect she is showing.
Now, you may feel that this is taking things a little far and what on earth is wrong with showing respect and if this is the fashion in which it is expected, we say “Why not?”!
Certainly more love, more abundance!
