I think children seldom consider how their actions and words can affect their parents. Unless you have parents like mine who will either smack you for a bad word or action or give you the dressing down of your life. Having said that, I also think the reverse also happens. Parents sometimes don't seem to consider how their actions and words can affect their children.
I know parents believe that when they want their children to do something it's in their children's interest. But they also need to realise that times have changed. What they know to be true might not necessarily hold true today. But have you tried telling that to a parent?
As parents, we do worry and we can only hope that whatever we have taught our children will benefit them in the future. But eventually we need to accept that once they have reached a certain age, they will have to be responsible for themselves and make their own mistakes. We have done all we could for them. We can only hope they've learnt something from it.
I just despair that many parents don't realise how their selfishness and overprotectiveness and greed could seriously damage their children. It may not show now or even later. But I do know that when it does, it's not the parents who have to clean up the mess. The children will be the one suffering. And I know from experience that what adults do to a child can seriously affect a child.
