I am the midle son of my family that recenly moved to Germany, as we had the security problem we coulden’t stay in afghanistan after ariving of Taliban becuse of the job we did in Afghanistan as volenteer in a Bmx freestyle cycling club for girls and boys for 5 years.
We are a quit family, now I and two of my brothers having German language course as well as my parents have too.
I would like to start cycling here and gym as well.
My brothers are having there goals as well, one of them like to start footbal amd the other would like to do the housbildung!
Mostly the the sons woulnt be at home, my mother would take care of house and my father during the day!
