In the real world, muggles are the senseless people who try to put you down. They'll demotivate you and not give you a bit of respect. Although remember, they do all this because they are scared that you'll turn out to be better than them.
Show them that no one can hide our special qualities, our strengths, and our superiority. If we bow to them, we will never find ourselves. But, if we stand up to them, we'll find something inside us that is beautiful and astonishing. So, don't let these bullies put you down because it's not worth it.
