‘You think I don’t want to walk barefoot on the dewy grass?’
     ‘Of course, you’ll walk on the dewy grass. And you could visit your relatives and friends’.
     She shrank from the thought that her son might go off into space and be lost to his relatives forever.
     ‘They’ve deepened our pond; it’s full of fish now, You like fishing…’
The astronaut replied to his mother, expressing his desire to walk on the dewy grass barefoot. His mother agreed with him, stating that he may go for a walk on the dewy grass and meet up with friends and relatives. She tried yet again to connect with him on an emotional level, but nothing should be able to stop him from completing his adventurous mission to another galaxy, as he only had a few days left.
She was afraid that her son would go into space and be unable to communicate with his family for the rest of his life. Despite the fact that she was unaware of her son's expedition, her maternal impulses led her to fear that she would miss him forever. She also tried to persuade him by saying that the pond in their location on Earth had been deepened and was teeming with fish. She then added that he like fishing, implying that she expects him to meet her on Earth.
