You know what? Just be honest; With yourself, with other people, with all the exchanges in your life. It is a hard thing to do. It is difficult to cast aside another persons feelings in favor of truth. For some of us it's a personal trial to be the villain. We always want to promote goodwill and positive vibes, no matter how much we HATE Mike from accounting. You become the problem and It really doesn't have a reward, (other than internal solace) but try it. Make waves in the house. Really have a day where you just are clean and up front about everything you say and do. Dole out hard, unpopular opinions. Unload heartfelt feelings. Honestly, play EVERYTHING straight. You may win friends and lovers. You may lose the very same. At the very least the air will be clear. JUST. BE. HONEST.
Altough, timing is important.
