Dear Mr. and Mrs Harris,
Welcome to our neighborhood.You must be excited to be in a new house.However,Would you mind turning down the music and not playing guitar too loud,Mr?Because it's noise to me.I can't stand the big noise when I trying fall asleep in the evening.And could you please not throw litter out of the window,Mrs Harris?It's easy to hurt others.As for your son,I think you will ask your son not to play football in the room,don't you?I hope you have a great time to be in a new house.Thanks Yours sincerely.
