Grandma stood at the window and looked and looked, watching her and him leaving little by little. She didn't know how sad her heart was, and what kind of beautiful life she hoped she and her brother would have. She was thinking about the line in the TV series; not looking back meant not looking forward to the return date, and thinking that if she turned back, grandma would see her tearful face, so she didn't look back... But this time she would never see her again in this life.
Intention: When you leave home, look back, smile at the woman behind you, and say something to reassure her.
