Apologize or Never Apologize

I remember the first time I apologized, I was just a kid. I was a few years old, I made a mistake towards someone (I don't remember everything exactly). My mother came to me and said "apologize" At first I thought it was a joke and I wanted to leave, but my mom stopped me and said "don't go anywhere until you apologize" then I felt like as I would press my soul, it was so hard for me to say those words, to apologize. But my mother was there and she kept telling me to apologize. At one point I said in my mind "if this is what they want me to do, I will do it ..... I don't think I will die .... there are just some words" AND here I am saying it "I ask you forgive me, I didn't want to do that, I promise it won't happen again, please forgive me "The words my mother urged me to say and I repeated it. Now here I am at the age of 31, and every time I make a mistake, no matter how small it may be, I feel the need to apologize. But in my life I have met people who have never apologized, do not know how to do it and do not want to do it. At one point, a person like this made a big mistake about me, and a few days later he told me ... "don't expect me to apologize because it won't happen never, if you want to forgive me do this ... if not, this is your problem, I will not apologize ".... And honestly I am, sometimes I sit and think ...... If this kind of People, they can't apologize to another man. How will they apologize to God when they reach the next Judgment ... ??? !!!
