Irresponsible parents

I had never seen such a parents like them before. Only bother about themselves, dont bother if their children are eating well, how's their emotion, how's their health and etc. Are u fit to call yourselves 'parents'!?
In school i have seen how parents wanna to run away from the payment of school fees, complaining about how teachers treating their child, seeing their child as the only precious one. But on this special kind of parents i seen, i cannot feel a single % of concern, love, worry, happiness, blessing, dote and responsible towards their children.
Sometimes i wonder, have they ever take a good look at their children?
Have they ever have a heart to heart talk?
Have they forgotten that the children's body do have their blood?
What do the parents seen the children as? A burden? Debt? Or just a outsider?
Seeing this kind of parents make me feel so sad for their children and i will remind myself never ever have this kind of attitude and behaviour if ever one day i have my own child.
