3．Dear Laura，
Thanks for letting us to stay at your seaside house． Now， you might have heard from your neighbors about which happened on Saturday evening． When I was out a walk， my younger son， Tom， played football before your house． He made so many noise that the neighbors got quite angrily． Even worse， Tom broke one of the window of Mr． Wilson's house． Tom and I apologized to all the neighbors for the unhappy happenings， but promised to have the broken window repair soon． Tom said that we would not do such silly things any more． I am glad that your neighbors had forgiven us． They are really nice people．
Yours，
