You parents showered you with a lot love and even without being told, you'll see everything they are doing and you'll also want to reciprocate the kind of love they showed to you.
A good parent deserve all the good things In life, because it's not always easy to cater for the needs of the children, the time and sacrifices they make all worth it, and you wouldn't want to joke with them, because they did not joke with you, the care you'll show to them will just come naturally because of the legacy they have portrayed.
It is not easy at all, they sacrificed their dream for their children... it is now that we have also become adult that we will realize their sacrifices and how it is not easy to take care of a child.
