pointlessly

They argued pointlessly for hours.

She wandered pointlessly around the park.

He spent his days pointlessly scrolling through social media.

The meeting dragged on pointlessly without reaching any conclusions.

I felt like I was wasting my time pointlessly waiting for him.

She stared pointlessly out the window, lost in thought.

He laughed pointlessly at the joke, not really finding it funny.

The project seemed to be progressing pointlessly with no clear direction.

She sighed pointlessly, feeling frustrated with the situation.

He kept asking pointlessly repetitive questions, annoying everyone in the room.
