I am collecting my younger child from school. my other one attending another school but is walking home alone ( about 2 km). Theey finish same time so usually I am on my mobile with my older one ( she is little scared to walk alone but I can't be 2 places at same time) while collecting younger one. recently the school told me I'm not allowed using phone while waiting outside school and while waiting for my child. It's taking 10 minutes (as the teachers talking to parents etc). Can they really prohibit me from using it?
