Her boredom was palpable as she stared out the window.

She stared boredly at the clock while waiting for the meeting to end.

Her boredness was evident as she doodled in the margins of her notebook during the long lecture.

By the third lecture I felt even boreder than before, so I started doodling in my notebook.

After six hours of waiting in the silent airport, I felt like the boredest person alive.
