I'm gonna let you in on a little secret. My best friend is a white woman I wasn't sure I wanted to be friends with. I worried a lot over whether she was worth it. When I met her she was in the "I don't see color" stage of racial develop,ent, and I didn't know if I wanted to invest the time and effort into being close to her because that meant I'd have to also teach her. But it turns out she is one of the best students on race I've ever met, and her care and learning came from wanting to be and caring about me as her friend because she wanted to learn how to be friends with me, and there's so much I would've missed out on if I'd made another choice.
I'm not the type to never want to be friends with white people. I will give it a try, and then decide if we'll remain friends, but I've been vetting whether or not we're going to be friends long before we ever speak. I'm the kind of black person who carefully watches white peoples interactions with each other, and we notice if you have interactions with PoC and how those interactions go. So sometimes long before you become friends it's already been decided what type of Black person you're gonna meet. Is it gonna be a deep long lasting relationship or is it going to be light and superficial?
Im not speaking for everyone but as a general rule we don't make "fast friends". If you've got real black friends (and associates) that means they think you're worth the effort, or they think you're genuinely nice.
