dear frined hope you are good , i am writing you this letter because i wanna tell you about somethig that makes me angry. The polution in my city is very high , I can't take it anymore i'd even think to tell my parents to move because is horrible here . I wish I could stay in a country side like you and breathe fresh air . In my city are too many cars that poluate the air . I Wonder what I can do to stop the polution because it is unhealthy for everyone ..if you have any idea please tell me .

I forgot to tell you not just the cars are a problem , there is a terrible smoke in the air but i don't know what makes it . Maybe other people can get used to it  but i can't .

I relly need a vacation where i can't breathe some fresh air so I Wonder if I can come to you if there isn't any problems ..I will be very happy

with love

your friend Ted
