Gray nylon tote bag with red zipper pull

I found a bag this afternoon around 3:15pm outside the Medford Public Library on Central Ave, near the main entrance. It's a medium-sized gray nylon tote with a bright red zipper pull and a small blue enamel wave pin on the strap. Inside there's a yellow lining, a spiral notebook with doodles, a stainless steel water bottle, and a cracked iPhone charger. The bag looks a bit worn but everything seems intact. If it's yours, email me at [email protected] and tell me a detail only you would know about the contents so I can confirm it's yours.
