Wet towel on the floor? Resist the urge to complain. While it's irritating, it will undoubtedly happen again...and again...and again. Instead, recite a modified Serenity Prayer: "I accept the things I cannot change."
You'll be amazed at how quickly your resentment melts away. Another tip: Try to air grievances at the same time each week in a formal meeting (no TV or phones). If you discuss what's bothering you in a structured, formal way, issues won't come up so often at other times, and if they do, you'll be able to discuss them more calmly.
