Your example literally means it’s what I forgot I didn’t do basically meaning that I did everything
Or in the future tense Se sa m bliye m p’ap fè – (literally, it’s what I forget I will not do) meaning that I will do everything.
Misye te tonbe joure m. Se sa l bliye l pa’t di’m. (notice past tense) – He began to curse at me. He really let me have it/ or He didn’t mince his words.
Another example of how it’s used:
John had not seen his wife for two weeks. When he called her on the phone to say he was coming home, he playfully said to her, Lè m rive lakay se sa m bliye m’ pa’p fè w. (notice future tense)- meaning that he’s really going to indulge with her.
