My grandfather is a musician. He started to play the piano when he was only 4 and he performed in a concert at the age of 13. He won 7 awards during his career. After he had grandchildren, he decided to get retired. In 2015, he moved to Izmir to live with us. Now, he only plays his piano on our birthday parties.
