I'm thinking of putting a complaints box in my kitchen. So my roommates can write down their feelings and then I can just leave them there. Or maybe I will start charging my roommates for every time they whine about the hot water not being sufficient. If you two would stop showering - and twice a day each - there might be hot water. Its not me. I shower a maximum of three times a week - ten minutes tops. Could I call the landlord? Yes. As my name is the one on the lease, does that make it my duty? ...maybe. Will I do something about it? No. Why? Because you two take too many showers and they are too long.
