Sorry , 7 years ago when the post system was really bad , I sent a letter to my self never recieved it , nor any other post , but lo and behold a big brown envelope was in my post box one day , yes you guessed it a letter and plenty of forms from the tax man !!!! and this is no joke , it is a standing joke to this day in our house .
Luckly we had nothing to hide !

so expect the unexpected here in spain !!!
