Splitting electric bill
So I have a new roomie joining me next month. He’s in the military reserves and said that he could be gone for months or a weekend. I’ve always split electric bill in half with my other roomie. In this case would it be unfair for him to go 50/50 if he’s gone for the weekend? How should I ask him without sounding rude?
Also with paper towels and toilet paper do you usually go half or something?
