Princess Celestia was the kind of pony that when something was bothering her, or on her mind, she’d put on a mask to cover it. It wasn’t to be rude, she wasn’t unwelcoming of ponies to come to her aid, either. She really did appreciate all the hard work her little ponies did to ensure she and her sister were happy and taken care of... but some things just needed… tact, a word Luna would use in all the wrong meaning.
