Let's take a painter and a canvas as another example. Without the canvas, the painter would have nothing to create his masterpiece on, no tool to accomplish his job. Without the painter, the canvas, would be blank and colorless, unable to do his job as well.
Evidently, one needs the other; it isn't called a pair unless there's two.
If you think about it, our parents are like this as well. They help us with the littlest things in life, to the largest. From helping us make our signature appear more professional; to helping us organize our room - they're always there. But when they fix these little mistakes for us, sometimes, they make sacrifices. They take something that belonged to them and gave it up just so we could have a better life. That's why, you should help your parents everyday, even if they are upset with you. Just like your parents do, try to keep them happy. But keep one thing in mind - the littlest things make them happy. There is no need to purchase anything - a love-filled hug will do!
Just show them that you need them, and that you are always by their side.
What happens next is not history, but a memory.
