I’m going to respectfully disagree with the anonymous sticker artist on this one. Quite the contrary, you will often find yourself regretting being kind. That doesn’t mean you shouldn’t continue doing it. Perseverance in the face of adverse odds is what makes you a good person.
The statement on this sticker though simply isn’t true. It’s a load of crap. Oops, I said I would be respectful, didn’t I?
