“How was your day?” “Fine.” “Good.” The exchange may be realistic, but a page of similar dialogue can leave a scene standing still. Before adding wit or a dramatic confession, give the speakers different small goals.
In this original writing exercise, one character wants to borrow a bicycle. The other wants to finish repairing it without admitting that a part is missing. Neither needs to say their goal aloud.
Write the goals outside the scene
Put one sentence at the top of your scratch page for each speaker. Then identify what each would prefer not to discuss. This gives you a reason for a changed subject, an incomplete answer or an offer that comes with conditions.
A goal need not be sinister. Someone may want reassurance, a quiet meal or enough time to decide. Small differences often give an ordinary conversation its shape.
Let an action complicate a line
“Take it whenever you like,” one character says, while turning the bicycle away from the door. The action can create friction with the words. Use such details selectively; a gesture after every line can become as mechanical as dialogue with no physical setting.
Keep the reader oriented. If a hand reaches for a tool, make clear whose hand it is and where the tool has come from.
Change something by the end
After a dozen lines, ask what is different. Has the borrower noticed the missing part? Has an offer turned into a joint repair? Has one person stopped asking? A scene can end with an altered relationship or understanding rather than a neatly resolved problem.
If nothing changes, try removing the polite opening and entering at the first moment of disagreement.
Read for voices, not accents
Check whether the speakers differ in what they notice, how directly they answer and how much they are willing to explain. You do not need exaggerated dialect to tell them apart. Record promising fragments in your writer’s notebook, clearly marking invented dialogue so it cannot later be mistaken for an overheard quotation.
