My first thought was that my roommate is making wine and I have not opened a wine bar?

I can see all the profits going up in smoke. I do not care if it is ancient brew that nobody drinks nowadays. If you want champagne, you can room with Joan of Arc or something. Or bring him about to sports or music event and save money on alcohol.

Plus you can loan him out for all the carpentry jobs. Need a table? Need a chair? IKEA is too far? IKEA's instructions are too complex?
