"Hey, it's sunny today," Emily said, smiling as she looked out the window. Her friend, Alex, was sitting next to her, sipping coffee. They were planning a day out, and the weather forecast was exactly what they had hoped for. "Shall we head to the park?" Emily suggested, her eyes sparkling with excitement. They hadn't spent a day out in nature for months, and the prospect of soaking up some sunshine was too enticing to resist.
