I'm lining up the nap mats and one has my mother's handwriting

I'm in the classroom after everyone's gone, and the nap mats are stacked like little folded letters. The third one from the top has my mother's handwriting on the tag — just my name, the way she wrote it before she forgot how. I keep smoothing the corner of it instead of putting it away, because putting it away feels like the end of something I wasn't done with.
