What fathers should let their children know: 1. Don't mind too much about people who treat you badly. No one is obligated to be nice to you in your life, except for me and Mom. As for those people who are good to you, in addition to cherishing and grateful, please also be more vigilant, because everyone does everything for a reason, he is not necessarily good to you because he really likes you, please you have to figure it out, and you don't need to be too quick to see the other party as your true friend. 2. No one can be replaced, nothing must be had, see through this, the people around you will no longer need you in the future, or when you lose everything you love the most, you should also understand that it is not a big deal. 3. Life is short, today you are still wasting your life, tomorrow you will find that life has begun to move away from you, therefore, the sooner you cherish life, the more days you will enjoy life. 4. There is no such thing as love in the world, love is just an instantaneous feeling, and this feeling will definitely change with time and mood, if your so-called favorite leaves you, please wait patiently, let the time slowly wash, let the soul slowly precipitate, your bitterness will slowly fade, don't overly look forward to the beauty of love, and don't exaggerate the sadness of falling out of love. 6. I will not ask you to provide for the rest of my life, and I will not provide for the rest of your life, when you grow up and can be independent, my responsibility has been completed. In the future, whether you take a bus or drive a Mercedes-Benz, shark fin or vermicelli, you will be responsible for yourself. 7. You can ask yourself to be trustworthy, but you can't ask others to be trustworthy. You can ask yourself to be good to others, but you can't expect others to be good to you as well, and how you treat others does not mean how they want to treat you. If you can't see through this, you'll only add a lot of unnecessary troubles. 9. As for the fate of relatives only once, no matter how many times you and I can see each other in this life, please cherish the time together, no matter whether you love or not, you will never see each other again in the next life.
