He just nonchalantly goes about doing it.

Tom smiled nonchalantly and didn't say a thing.

Tom got up and walked nonchalantly to the door.

Three hours later, the King was loitering around the castle, looking for something to busy himself with. "Fuck, I'm so bored," he grumbled in exasperation. "The kids are at school. Gwo's at work. Impa's at the hospital. Ganon—" Suddenly the King heard an incomprehensible cry and turned around to see Fari rush past him. "Damn, Fari, what was that?!" "Piss off, Your Majesty!" Fari yelled at the top of his lungs. "My... PMSing as usual, I see," the King continued to mutter dejectedly. "Shit, I'm so fucking bored. Nothing good on TV. Nothing good online. Nothing good to eat." As he was about to leave the dining hall, his eyes were drawn to a cinnamon jar standing lonely on the table. A spoon of cinnamon was placed conveniently next to it. In a saner state the King may have been reasonably suspicious about it, but now he was so exhausted from boredom that any opportunity to relieve it for a minute felt like a blessing. "I wonder what ground cinnamon tastes like," said he nonchalantly and put the spoon in his mouth.

I wonder what ground cinnamon tastes like," said the King nonchalantly and put the spoon in his mouth. "Hmm? ...Shit! Water... water... in the fridge. Oh crap, no water in the fridge!" The King went on running around the room frantically, looking desperately for water. Luckily, Duke Onkled happened to be pouring himself a glass of water. "Your Omnipotence, have water," he offered dutifully. "Gimme!" demanded the King, then emptied the glass in a split second. "Damn, that was awful."

Subsequently, she started screaming and breaking vases. I, in turn, nonchalantly left the apartment, and went to have tea with Mary.

Chokichi keenly felt that people, as they get older, forget entirely about the worries that only young people know about and that they themselves experienced in their youth; and that they nonchalantly take this convenient disposition where they judge harshly the circumstances of the young persons born of the next generation. He felt that there was truly an irreconcilable gap between the old and the young.

Tom walked nonchalantly.

Tom leaned nonchalantly against the wall.
