What is something you realized lately that you didn't realize before?

I was on FB chat with an old high school classmate. He sent me a video of him dancing very recently. He said, “I may be old but I still got some moves!” And he did. He’d go all the way to the ground and back up. I told him I’d dance with him, if he held my hand so he could pull me back up!!
I put in a muscle arm a heart, then went looking for an emoji of two people….and suddenly realized, all the people emojis are WHITE. My classmate is black. I wouldn’t have even realized about the emojis if I had gone specifically looking for an emoji of a black guy.
:(
It must be hard to be black and to see examples of this kind of casual, unthinking exclusion everywhere you turn.

Please don’t start sending me obscure emojis of black people. I was stuck with what FB had, which is basically what my phone has too.
