Conversation with my new roommate:
There are two of them because they're for electricity and gas.
It's higher because you don't use exactly the same amount of electricity every month.
Seriously, have you never paid a bill before?
There's another oil bill because they delivered more oil.
Have you noticed the house is warm, and we have hot water? It's nice, isn't it? It's not free.
No, I don't know when they'll cash the check.
Please don't make me do this every month.
