The older I get, the more I want to be honest with people (without being a dick about it) and have them be more honest with me (ditto, non-dickishness).
Being married, I find that, in order to not be a dick, sometimes just letting it go is better than honestly. I’ve learned that, even if my SO did something incredibly stupid, I don’t have to call everything out unless it’s affecting our lives negatively.
Not even a couple of years after being a teenager, and I find being honest with myself and others to be one of the most rewarding things I can do. It just makes me very happy with everything.
