You don’t know how other people will accept words you say by mistake. I believe that you can change a life with just one word. If I feel that I’m in the wrong then I apologize no matter what. If I happen to slightly brush past someone on the street I say that I’m sorry first. That’s what my parents taught me to do since I was young. To always greet the security ahjusshi even if I see him several times a day. I think the inner thoughts that I formed as I lived like that have made me who I am.
