The apology letter Dear Jason, Please accept my apologies for making noise recently. I have been moved here for two weeks, so I invited my friends to visit my new apartment. There were also some children here, it was a little bit hard to make those children to sit quietly. Also, I was too exciting to move into a new apartment, I lost control to spoil myself with my friends. The party kept on in the whole night. In regard to the noise occurred, I can assure you that the noise will not happen later, I will keep the matter in heart to alert myself. It would be grateful if you could also provide your sleeping period for my reference, so that I can verify no noise making during that period. Best regards, Marco
