As writers we're often exhorted to 'show not tell', but that old maxim can be deceiving. Certainly 'showing' is great, but we need to remember there's often more to showing than what our characters can see.
Imagine your character is walking down a hallway. Of course she can see the walls and any decor, but what about her other senses? Is there the faint aroma of furniture wax or perhaps a whiff of another woman's perfume? Is there the reminder of last night's fish dinner in the air, or does the heavy dust of a long-abandoned hallway cause her to sneeze? Or maybe that sneeze is because of her allergies; letting her know that a dog or cat is somewhere in the house.
So our character is walking along the hallway, but what does she hear? The creak of floorboards might be spooky or might tell her that her husband still hasn't gotten around to fixing the squeak in the floor. Maybe she hears a radio playing and she knows she didn't leave a radio on. Maybe she can hear the rattle of pans in the kitchen informing her that her beloved boyfriend is cooking her dinner.
Do her shoes sink into plush carpeting? Does she trip over a wayward toy left by a small child? Does she run her hand over the paneling in the hallway counting the grooves since the light has burnt out and the hallway is dark?
Don't forget taste as it can play a part as well. Does she just realize her gum has gone stale? Did she find a chilled martini waiting for her on a hall table? Or, were her taste buds readying themselves for dinner only for her nose to tell her nothing is cooking?
Sometimes walking down a hallway is just a way to get to another room. But sometimes, what our character experiences in that hallway can be the beginning of a whole new chapter.
