Sharon can barely recognize the car pulling up in front of her house. The rain is streaming down the windows in sheets while the panes rattle with each growl of thunder in the distance. Despite the early hour, the darkened sky makes it appear like night-time outside. Hearing the doorbell, she goes to the door eager to discover who might be out and about on such a gloomy day. It is her friend, Jill. Jill asks her to hop in her car for a trip to the mall. Thinking it's an ideal rainy-day excursion, Sharon jumps in her car and fastens her seat-belt. Arriving at the mall in a few minutes, the two girls quickly locate a parking space and run inside. The mall is nearly empty. Smiling at the girls' stroke of genius, the girls begin walking down the corridor. Sharon's shoes make a smuck-smuck sound as the they slowly shed water in a series of wet footprints. Shaking the water from her hair, she suggests a cinnamon cappuccino as an antidote to the wet weather. Seeing a nearby coffee shop, she leads the way. What a perfect way to spend a rainy afternoon.
