Hello , :) .

I'm going to imagine that I studying in America and I have made a new friend so I'll write a message to my father to tell him about my new friend .
( That is a trining for me to learn the writing skill )

Dear father ,
How are you dad ? . Sorry I haven't seen you for ages but I have had masses of work ! . My study is going really well , though .
I have just met a kind friend his name is John . He is 22 years old but he looks younger . He has an attractive character . He also very energetic person and very adventurous . He lives with his family and I like his little brother . He is an excellant mechanic and works in a small work-shop so he fix lots of car daily . He likes vally ball and reading but he doesn't like rock music . This morning he helped a blind to go across a street so that is why I like him , He helps his friend when they need it .
I hope see you soon .
