Could you please give some examples of this?
Because she has always been a gracious and respectful competitor. She has taken her losses in her stride and used them as a motivation to improve. She has never inappropriately blamed anyone else for her losses. And, she has worked hard to be the very best that she can be as a skater, never letting criticisms of her and Eric get to her (and there have been many).
In addition to that, she is a vegan who has great respect for animals and is involved in dog rescue (rescued one from the dog meat trade last year and another one after this Olympics). Maybe 'class' is not the right word for these actions, but I think they certainly merit much respect for Megan.
Nope, you most certainly will never have to worry about anyone calling you classy.
