For days, I’ve been criticized by my girlfriend for not remembering our anniversary (’for’ 帶出的完成式), which happened to be last Wednesday when I was locked in a meeting till like 10 that night. By the time I left the meeting, I realized she had called my cell several times but left no messages (過去的兩件事，先發生的用過去完成) .
Since my cell’s battery was running low (強調當時), I figured I would ring her later (在過去時間的未來式), so I took off. But the call slipped my mind when I got home. Exhaustion got the better of me. That turns out to be one big mistake I should’ve avoided, come to think of it (回顧已發生事件的).
