Teachers teaching in Primary wing must have some sensibility that they are small children and sometimes they are not able to tell or forget to tell parents about their activity,project etc.,  for the materials( which are not so very costly ). Teachers have their own ego that they are teaching in DPS but they dont know childrens couldnt forget the events happening in the class . They just say zero infront of all children and then the child suffer.  

They must have some sensibility while dealing with childrens... that some teachers teaching in DPS  must take training. After all it is someones child,their life.. before abusing a child and handling the matter in a egoistic way which they doesnt deserve....

First they should learn abou the proper communication  then harass......
