A colleague had the call we all dread, her teenage son had been the victim of a crime involving a knife, although by the time she got the call it was all over and he was, thankfully, physically, unharmed.
She had been in the process of changing out of work clothes into her comfy stuff when the call came and dashed off to get him wearing just sweatshirt and underwear.
To be clear, I'm not judging, I admire her commitment and she tells this as a funny story, but I do think I'd have got dressed first, perhaps making me a less committed mum? TBH there's every possibility I'd have ignored the phone and called back, if I was getting dressed 
What would you have done?
