Mika Kobayashi:  What are you doing ?
Daigo Kobayashi: This one . Here .
Mika Kobayashi: What ?
Daigo Kobayashi: A stone letter .
Mika Kobayashi: Stone letter ?
Daigo Kobayashi: Long ago , before writing , you 'd send someone a stone that suited the way you were feeling . From its weight and touch , they 'd know how you felt . From a smooth stone they might get that you were happy , or from a rough one that you were worried about them .
Mika Kobayashi: Thank you .
Daigo Kobayashi: What did you feel ?
Mika Kobayashi: Not telling . That 's a lovely story . Who told you ?
Daigo Kobayashi: My dad .
Mika Kobayashi: You mean ... that big rock ?
Daigo Kobayashi: Yep . I got it from him .
Mika Kobayashi: I did n't know that .
Daigo Kobayashi: He said he 'd send me _ one _ every year , but that 's all I ever got . That jerk !
