A parenthesis can make a sentence sound as though the writer has leaned sideways to add a private remark. That effect is useful when it is chosen. When every other line contains an aside, the reader may struggle to find the main voice again.
Read the sentence without the brackets
Try this invented example: “Mira returned the blue mug (the one with the crooked handle) to its shelf.” Remove the parenthetical words. The main sentence remains complete. That gives you a practical test: the aside adds something, while the main grammatical route survives without it.
If removing the aside destroys the meaning you most need to convey, consider bringing that information into the main sentence instead. Essential explanation should not have to hide in a side room.
Ask what the interruption contributes
An aside might narrow a reference, complicate a claim or reveal a speaker’s attitude. Choose one job. “The one with the crooked handle” identifies the mug; “as if anyone would miss it” changes the narrator’s tone. Those are different revisions even though both fit between brackets.
Check the rhythm of the paragraph
Read aloud with a slight pause around the aside. Does the sentence resume naturally? If several parenthetical sections compete, keep the most useful one and move or cut the others. A separate sentence may give an important qualification the attention it deserves.
Use reading a paragraph aloud to check the result in context. Parentheses are not a requirement for conversational prose. They work best when the brief detour gives the reader something worth carrying back into the main sentence.
