The Use Of the Mute Function

After a night of unsettling dreams (long, empty rooms with doorways leading into menacing darkness; realizing I had done something to hurt Katie's feelings; going outside without a mask and being unable to enter a nice restaurant while people walk by and glare), I wake up to a Facebook thread of two people I know from high school arguing.

He's a white guy, angry about something that happened when they were teenagers, and she's a black woman, angry about him being a white guy and accusing her of that thing that she claims she doesn't remember. I don't know either of them at all these days, but I do remember her being kind of mean when we were kids (I'd certainly never mess with her!), while he and I have kind of fallen out lately. 

The whole thing is like a long, angry car wreck, and even though I have no idea what happened, and reading it makes me feel like I drank battery acid, I can't look away.
