That night with Hamtaro...

Hamtaro hurried back into his carrier as he heard Laura come upstairs. He made it in time to his carrier and Laura came into the room. "Hamtaro!" Laura exclaimed. "I'm going to make Mom a new apron since she cleans a bunch." "Heke?" Hamtaro said.
Laura got Hamtaro out and put him on her desk. She pulled out her journal and started to write in it. Hamtaro ate a few sunflower seeds and started to think of the day. I wonder what's wrong with Boss, he thought. What could be wrong? Did someone say something to him? I know he's really sensitive sometimes. But why would he be sad?

On Saturday, the day before Mother's Day...

Hamtaro arrived at the clubhouse extra early. "Boss!" he shouted, but Boss wasn't in the front room. "Where could Boss be?" Hamtaro asked himself. He opened Boss's bedroom door and found Boss in bed. "Are you sick, Boss?" Hamtaro asked. "No," he replied in a whisper. "Then what's wrong?" he inquired. "Hamtaro," Boss whispered as he sat up. "Can I tell you something you can't tell anyone else? Well, you know how I said I had a mom all week..."

Later that day...

The girls were still outside knitting and making their owners and Mrs. Montgomery something for the next day. All of the boys had something for their owners. Jingle had finished his card for his mom and sent it through the mail.
Howdy realized Boss hadn't made anything and said, "Where's your gift for your mom? I wanna see it!" "Err..." Boss muttered. The girls came in the door. "Where's Caitlin?" Hamtaro asked. "She went home to get something," Sandy replied. "Back to your gift, Boss," Howdy remarked. "Uh..." Boss muttered. "Wait! You hate your mom and made a card saying 'I hate you'! Isn't that what it is? Huh?"
