Gray tote bag with pink interior and tassel

I lost my gray tote bag yesterday around 3pm near the Columbia Center Mall parking lot on Columbia Center Blvd in Kennewick. It's a medium-sized nylon tote with a pink satin lining and a tiny pink tassel charm on the zipper. The bag shows light wear at the bottom but is otherwise intact. Inside I kept a small spiral notebook, a blue water bottle, and a coffee-shop sticker that says 'Columbia Cafe'. A white enamel cat pin sits on the strap for easy identification. It means a lot to me; it was a gift from my grandmother, and I really need it back.
