Summer is here and I’m practically broke because of my roommate. Diane moved in at the beginning of April and since then our electric bills have been through the roof because she sets the thermostat at 66°. I always kept it at 75° or 76° before she moved in. We agreed to split all of our bills evenly. I had no idea that she is always warm and needs the air conditioning so low. When I asked her to pay more of the electric bill she refused saying we already agreed to split every bill evenly. I think it’s unfair. What do you think? Should Diane pay more of our electric bill or not?
