a story that been told..

There is one day a father asked his son to help him to carry his very old grandfather to the hill and leave him there. The father think that the old man is useless and can't help much but just consuming their food. Therefore he decided to leave this old man alone till death at the hill. So his son..knowing nothing, helped his father to get this old man into a basket and brought it up to the hill. Once reached the hill, the father said. "All right, just leave him here will do,leave the basket here as well" Then the son said "No,we need to take back the basket so that next time when you are old that time, i still can carry you using the same basket. Don't waste it.."
Once the father hear this, he immediately carry back the old man back to the house and take good care of him.

Well..treat your parents well..they deserve to be treaten good. Without them, you wouldn't exist. You only get to have one chance..and you might face the same on what you had done to them by the time you are old.
