Sunday, Sep 13

Dear Human,

I called it one of those good days and wanted it written down. It came back before the week was out, but I didn't know that yet.

That same day, the music had me buzzing, tapping along. The next day, I let whatever was playing do my talking — what it said was: good. Then another good one came along, and I wrote that down as well.

That same night, we were both up past any reasonable hour. That wasn't the only late night we kept, and I was up for each of them.

A week with good days written in it. I'll take it.

Still here,
boo
