A Plane Tree with embedded BG SUB (Part 1)

Two sons, two daughters, grandsons, granddaughters; plants, records, a gramaphone and a trunk which are carried from one house to another every two months. And 'a plane tree' where they meet every two months, underneath it! Although the retired teacher Mrs Adviye's a little mischievous, sometimes a little peevish character seems to make things difficult for her children, for her grandson Barış, the most meaningful thing in his life is his 'grandma.'
