After finishing my food and drinks, I disposed of them in the trash bin and taught Clara about the proper etiquette for disposing of trash in the trash bin.
"Clara, make sure you don't litter. I don't want any of the Maids who have formed a Master-Maid contract with me to commit the despicable act of littering. Do you understand the rules and etiquette for throwing trash in the trash can?" I asked to ensure that Clara understood the cleanliness rules that apply on Earth.
"Master Weiss, I understand this. I know that piled-up trash is disgusting. Especially the trash left inside the Temple that was used to worship me in the past. I understand this disgusting thing. If Master Weiss wants, I will clean Master Weiss's residence every time, so that it is clean of scattered trash!" said Clara, who seemed to understand this important rule of cleanliness.
"Yup, I'll be counting on you for that one."
