The coffee Cup still Steaming

"My mom was sitting at the table, just like always, hand around her coffee cup, and it took a while to register that this shouldn't be happening, that she's been gone some time now. sat down across from her anyway, didn't say anything about it, like questioning it would make her disappear. She talked about nothing really, small stuff, her voice exactly right, and I kept staring at her hands more than her face. wanted to say something real, felt it building in my chest, but every time I tried it came out as more nothing. At one point I said something like "wait, aren't you" and she just smiled past it, got up for more coffee instead. The kitchen shifted a little while she was up, not quite right when I looked again. I turned back and she was gone, chair empty, cup still steaming like no time passed. I didn't look for her, just sat there, that heaviness pressing down. I woke up with it still sitting on my chest a while."
