MPSOX you assume that if a Principal has to ring a pupils home that
1. they have a phone
2. there is someone there
3. they can come to collect the child
4. they give a damn
I've no doubt that there may be occassions when a parent may be uncontactable, but if the parent doesn't give a damm or deems something else to be more important then the welfare of their child, then the next call should be to social services or the Gardai reporting a child in danger.
