It has been raining since the first day of (the) Chinese New Year. Partly because of the rain, there was less traffic than usual (no comma after the main clause) when I drove to a park located at the center of the city. I quite (in the US, we'd say "really") enjoy driving on empty roads, which is very uncommon here in the city. When we arrived, it (or "the rain") turned to a drizzle, so we got out of the car and took a walk. It was chilly, and Isabella didn’t hadn't (or "wasn't") dressed warmly, so we got back into the car.
