Well, at least she had hoped her parents would deem their wedding anniversary something more important than work. It was their wedding anniversary for Christ's sake! If they did, skip their anniversary for work then Lady Melissa might as well snap.
She knew it wasn't in her position to snap or anything but it was their wedding anniversary, and as much as she had respected their wishes and knew her boundaries, she would be a little angry at them.
Yes, work was important but it was a wedding anniversary, their wedding anniversary, Lady Melissa would never understand why they would skip such an important event to do work if they did skip their anniversary.
Lady Melissa had hoped that they really wouldn't skip out their anniversary since then everything that she had prepared for them would go to waste, and they wouldn't even be able to relax, even if it was just for a few hours.
