It doesn't matter where you go. Everywhere large amounts of screaming children can be found. The parents seem either unwilling, or worse, unable to do anything about their little bastards. The children in and of themselves do not offend me, it is the excessive amount of noise they generate that gets to me. We are not talking about babies here, we are talking about ones old enough to know better. Something must be done.
The parents should be silencing their children, or at least teaching them not to scream at all times. Electric collars would be a nice way to keep them quiet, few thousand volts every time they get past a certain level of sound. After 4 of 5 shocks, they would not be screaming anymore. Or a good well timed slap would serve just as well, but it would need to be while the child is making the noise, or the child may not understand why it is getting slapped. In general a parent could do much to prevent the noise.
If the parents are unwilling to take discipline in to their hands (in which case they should have their children taken away, but that is another blog) then the other people at the store should be allowed to fill the role of disciplinarian. Low power cattle prods could be carried into store to keep loud and annoying children inline. The stores could have the security guards roam the isles with duct tape, a few layers of that would teach a child a valuable lesson. If these methods fail, we could train large dogs to attack anything making to much noise, sure some kids might not make it, but is that to much to pay for a quiet shopping experience.
In the end, we just need to make children understand screams are for seriously bad things, not everyday. However, if they must scream, why not give them a reason?
