Dear Mr and Mrs Harris,
welcome to our neiborhood.you must be excited to be in a new house.However,would you mind not piaying the guitar and singing too loudly?it's too noisy.Although your voice is really very great.and i know your son can play soccer very well.But would you mind asking your son not to play football in the room ? And Mrs Harris always throws the litter out of the window . I think you should clean the yard as soon as possible. And would you mind telling her not to talk on phone loudly? That makes me have a hard time doing my homework carefully all the time.
I will very graceful if you really do that .Thanks.
