"Mommy! You have to wait for us. You have to…!!" little Sera's voice was full of pleading as she gripped the phone with her slender and cute hands, large eyes widened and sparkling with unshed tears as she heard her mother's gentle laughter coming from the phone. "Wait until we arrive before taking the baby out! We have missed Yu Kai's already. I don't want to miss this one too." Sera reminded her mother insistently, afraid that she might forget. She knew that her mummy was a very successful and busy medical scientist and had lots of work to do. So, she was helping to remind mummy.
