The way you say things in your head Hully (and others) is obviously very different to the way they're said in context.
Familiarity is important. I wouldn't call you Hully a young girl, because it offends you and I have some sense of self preservation. I wouldn't call a stranger 'love'. I am more familiar with liked and respected colleagues, and even more familiar and cheeky with friends (and they me).
In THIS context, the butt of your whole arguement, I do not feel anything other than a deep respect to those particular police officers was shown, and a deep and genuine fellowship.
Because I call my mate a young boy, in a tone and context you cannot possibly understand, its ME who needs medication? Nice Hully, well done, bravo.
As whether its EVER acceptable to call a 32 year old woman a young girl, yes, sometimes it is.
