Teachers are in the middle of the conversation on racial injustice, poverty, bias. I encourage you as you enter the field to consume every bit of the conversations going on today. Every video, every tweet, every post, article, film and book on the subject.
And when you are done with that, then go to your friends and listen to their fears and concerns. Really listen to them. Do not just take it in; but put yourself virtually in their shoes and think of how that might make you feel if it happened to you.
