Actions speak louder than words, man. If what you say about yourself is true, you'd see no need to be defending yourself, you wouldn't see the need to prop yourself up like you just did and create this wholesome image of yourself like that. You might look a little closer at that day, see where you went wrong, maybe offer an apology which wouldn't be necessary but is something people do in those situations after making mistakes. Things like that.
I don't hold a grudge. It's whatever. Hopefully you can take a joke someday.
