He didn't do well on the exam, so at night he lay in bed reflecting on whether he had been too playful lately.

After arguing with his girlfriend, he sat alone in the park reflecting and felt that he had spoken too harshly just now.

Every night before going to bed, he spends ten minutes reflecting on his words and actions of the day to see if there is anything he needs to improve.
