Why I did not have my science workbook

Dear Mr Wan,


I am sorry i did not have my science workbook.I did not hav my science workbook as i had left it under my table. As under my table also had alot of other stuff the science workbook fell out and that was why i could not find it at home nor in schoool . This is the reason i did not bring my science workbook was that i could not find it at home the day before.I am very sad and dissapointed at myself and i hope that you will forgive me.
