Threatening his mother

Brian barged into the office with an assistant who was running after him. With her erratic breath, she explained fearfully, "Ma'am, I– I couldn't stop him."

The sophisticated woman slowly looked up from her laptop and waved her hand to dismiss the lady. After she left, Nancy folded one leg on the other as she stared at her angry son, then her eyes moved to the gun he was holding and raised a brow with her lips stretching into a small smirk. 

"What brought you here?" 

"Why did you kill her?!" 

"Do I need a reason to get rid of a thorn in my flesh?"

"Mother!!" he screamed, then ruffled his hair out of frustration. "What was her crime?" his voice lowered, almost like a whisper while controlling his tears.
