谁会写一篇英语作文，要求是你的好朋友邀请你去参加她的生日聚会但是你有事不能去，你给你同学回一封电子

hi ,xx,I'm sorry to tell you that I may fail to attend your birthday party ,for I got something to handle that day .You know that the final exam is approaching right ,I have a hard time focusing myself to study ,so I guess I may just have to stay at home and preparing for my exam .What's more ,my mum went out and left my little brother at home ,I have to take care of him .What's worse is that my cloth for party has been dirty and kept me from going ,I knew you've been longing for me to go ,but I just have to say sorry ,have a nice day and wish you happy birthday !
