I walk my dog in this park nearly every day, at least for sure in the morning since it's been so hot.
Sometimes we sit and have a cup of coffee or a lemonade (for me, of course; she gets water) and I read the newspaper.
The other day I noticed that someone had gone off somewhere and left glasses, a book, and a notebook, along with his/her water. I thought at first the 'writer' had gone to use the restroom, but he/she never returned in the 45 minutes I sat there.
