The 7th day

It'd been 7 days already,still havent tell the truth...
im so sad of it,but today,my teacher had taught me a sentence,
a phrase,called -> Let Bygones be Bygones,
I got shocked of my life because,
My teacher had told me the real life being,
Im so sad,I keep endure it and avoid my tears flowing out,
Haiz,mayb,mayb she had forgot me,
hha,I dont know I'm happy or sad,
Hha, :'(,
Let bygones be Bygones,I think,I have to use a long time to understand it...
The 7th day...
