People always say “It costs nothing to be kind” but technically it doesn’t cost anything to be a real asshole either, so I’m not sure why we’re bringing financials into it. It does, however, cost money to hire lawyers after you stab people you don’t like in the leg so maybe that should be the phrase everyone should remember. Then again, if you bottle everything up and continue to be kind to people who are being real dicks you’re going to end up in some pretty heavy therapy or in a lot of bars drinking your resentment away and I can tell you that neither of those things are cheap. Really they should just change the saying to “Life is already expensive. There’s no need to make it worse by being a dick to people.”
It doesn’t quite sing like the first line, but it’s more accurate.
