Regret. That is all he felt now. Self-loathing and regret. It bubbled inside him until he exploded, shouting and screaming at his wife and young children. He loathed himself for being such a monster. He shouldn't have screamed at his wife when she asked him was he alright. He shouldn't have shouted at his children when their only crime was laughing with pure happiness. But most of all, he shouldn't have ignored her when she found herself surrounded by girls teasing her.
"Girls will be girls", a voice taunted in his head sounding earily similar to him, "That's what you said didn't you?". He shuddered as he recolllected walking past her being tormented. He had easily dismissed it, his mind on other things. He should have stopped them and asked them what were they doing? But he didn't.
Other flashbacks attacked him as his hands shook. The first flashback was of the day she cried silently in class and he ignored her. Another was when she came into class disorganised with messy hair and tear tracks on her face. He had yelled at her and grumbled about her to the other teachers later in the staffroom.
He was her teacher and he had failed to protect her.
Regret... a silent killer
