I don't find it odd at all - people forget that they are looking at things in hindsight!!
I don't want to be a fly in the ointment here, but I find it frustrating that you are implying what I am saying is in hindsight.
"come quickly your sister has gone berserk, and has the gun". Now how clear is that.
I will just call Julie, then two calls to police stations before I dress. Hindsight has nothing to do with it.
I can comfortable state that I would have dialled 999 [why didn't Ralph?], or would have responded to the call. Hindsight has nothing to do with this Caroline IMO.
