I don't think it's entirely untrue but if you expect to receive kindness after giving it you may end up disappointed. Being kind is in my nature but I am not always like this. I have my bad days too lol bc human. I like to think I'm a good judge of character and don't usually expend energy on people who don't make a good first impression on me. I will usually be cordial and respect formality but If I don't like you I probably won't give you much of my time or attention. Being kind is inherent for me.
