Hi Nickos, do you or have you ever had teenage children? Anyone who has will be familiar with 3am phone calls I would think. 
Hi maggie,
I have three children, 24 (son) 18 (son) & 16 (daughter).
No 3am phone calls as yet, either way, but which way do you mean. Them calling me or me calling them.
I certainly would not call my 24 year old son over to a situation that would bring him into danger at any time of the day never mind in the dark and at 3am.
I would deal directly with my daughter and if she was emotionally disturbed and holding a loaded gun
(both of which are not thankfully I have not had to deal with) I would attempt to disarm her, physically if needs be, not only to protect her from herself, but also to protect any other loved ones in the house.
I have an air rifle and know basic gun rules - one fundamental rule is never point even an unloaded gun at anyone - even in jest.
Nevill would have done anything to disarm sheila if he had been able to - even injured - she was after all alleged to have gone crazy and had a gun!!
Who would go and make a phone call, never mind two, in this situation - leaving her alone with a loaded gun - unbelievable imo
