A letter from Australia

Alex, an 18 years old boy from Britain, wants to meet his father in Australia.
He hasn´t seen him since he was 3 years old.
He writes a letter to him and gets the answer: His father is looking forward to see him in Australia.
Alex is very happy, suddenly he is able to remember the nice time he had had with his father.

I am sure, it is not simple to write a letter to a father you do not know, wich you can not remember.
It is very nice, that alex mum helps him to see his father. Other mums would not like it because they were afraid that their child could like the father more and want to live at him forever.
