This evening Martin heard neighbour kids 哥哥姊姊 riding bikes outside, then he insisted to go out. We took Martin's ㄅㄨㄅㄨ(car) out. Neighbour mama Amie saw Martin wanted to play with big brother and sister, so she went inside house and got her daughter's tricycle letting Martin to try on. He likes that 4 years old boy so much. Finally his dream came true to join them and no need to watch and call GeGe only.
