The thing is that love gives us a ringside seat on somebody else's flaws, so of course you're gonna spot some things that kinda need to be mentioned. But often the romantic view is to say, 'If you loved me, you wouldn't criticise me.' Actually, true love is often about trying to teach someone how to be the best version of themselves.
It is hope--with regard to our careers, our love lives, our children, our politicians, and our planet--that is primarily to blame for angering and embittering us. The incompatibility between the grandeur of our aspirations and the mean reality of our condition generates the violent disappointments which rack our days and etch themselves in lines of acrimony across our faces.
