I respond to the following commands:
🏠 "buy a house" :
I will build a house for you in MastoCity. If you already have a house, I will tell you where it is.
🏘 "move in with @name" :
You request to share a house with @name. Someone already living in that house must accept the request by answering "yes". Moving in with someone only works if you already have a house.
