By whom? In what circumstances?
Sahar when mommies and daddies work the kids are left in the care of babysitters and daycare people and maids. I do not know about how it is done in the US but over here and in Pakistan the parents leave their kids with the maids and they are busy doing their things and do not look after the kids properly and niether do the kids get the properly love care and attention that they need from their parents. I have seen many cases of people who were mentally disturbed or did crimes because they were deprived of maternal and paternal love and also because they harboured this revenge like instint against their parents because they were not there for them when the kids needed them in childhood. Later on when the child is all grown up and does things on his own he/she says mai aap ki baat kyon suno? aapne kya kiya tha mere lye? where were you when i needed you? aap tu mere sports day par bhi nahi asake/asaki!
