You can understand this, which means you are really mature. Parents are selfless to their children. Until their death, they still cared about their children. When you get married, she (he) will cry. When you were bullied outside as a child, he or she would go to the bully to judge you. I'll carry you to the hospital when I'm sick. When your work and study are not smooth, I will sit next to you to help you solve your worries. You have made achievements bit by bit in your work and study.
I believe that few children don't understand the love their parents give us. Like you, I also live a long and healthy life for all parents in the world. Wish your parents a long life. When they are old, they should not be allowed to work!
I hope my answer can help you!
