It was evening. Ferlin Eltek was in his study looking over the newly issued textbooks when he suddenly heard someone knocking on the main door.
"Dear, I'm busy toasting bread. Why don't you get the door?" Irene shouted from the kitchen. "It could be Miss May."
"Okay."
He closed the book, walked to the front door in the living room, and unlocked the latch. The person standing outside caught him completely by surprise.
"Father! What brings you here?" Ferlin exclaimed.
"I followed His Highness here," the old knight said while brushing off the snow on his shoulders. "In fact, I arrived in Border Town yesterday. Though I told them that my son is living here, they still arranged a house for me in a residential area near the castle."
"Come in. It's cold outside." Ferlin hastily moved out of the way.
"Yes." The knight seemed surprised as he stepped into the house. "You have... central heating in here?"
"You know central heating?"
