My son had a school project where he had to write a letter to a well known person. I'd say he picked a good man in that sense;
44th President of USA, Mr Barack Hussein Obama II, born 4 August 1961 at Hawaii, is fairly well known around the world.
The letter was sent to the White House at 1600 Pennsylvania Avenue, NW, Washington D.C 20500. Let's see if there will be any reaction...
When taking it to our local post office, the officer noted "wow, this is to a special person" and put a label on it - something they don't do normally.
