- Talk to each other. Make sure resentments don’t build up. Fights can happen that way.
- Have respect for the other person’s things. Don’t borrow without asking and try not to move their stuff around if possible.
- Be polite. This goes a long way. Say please and thank you. Ask before having company over and don’t be loud late at night. It’s only fair.
- Realize you’ll have to make sacrifices. Nobody gets their own way all of the time. Nor should they.
- Clean up. You don’t have to be spotless all the time, but do a little picking up every day.
- Give the person a little space. Everyone needs some alone time.
- Be nice. Once in a while spring for dinner or buy the toilet paper without being asked. A little bit of goodwill goes a very long way.
