You're back in elementary school subtracting lines on a chalk board.

你回到了小学，在黑板上减去线条。

You, with your voice like nails on a chalk board calling me out when I'm wounded You, picking on the weaker man.

当我受伤时你用你指甲刮黑板似的声音冲我喊叫你最喜欢欺凌弱小。

In another experiment that pulled 400 people, 20 percent reported that moist gave them the same reaction as fingernails on a chalk board.

在另一项有四百人参与的实验中，20%的人报告说，“潮湿”一词使他们产生的反应就像指甲在黑板上的反应一样。
