As I was going in to the gym at lunchtime yesterday some poor chap had a seizure in there and was taken off in an ambulance 
Today I got stuck at the toilet sinks with my awful fishwife colleague (I avoid her as much as possible) who with glee announced loudly that I had "missed all the excitement at the gym yesterday" 
(she was at a fitness class in a studio there that I sometimes attend but I had just gone to the gym instead)
She went on to recount how when they arrived they "saw the guy being put in the ambulance and oh he didn't look very well and oh well they had to cart him down in the lift and bring him out through reception and everyone saw him and oooh he didn't look that old and we don't know what happened" (without taking a breath)
When she had stopped wittering I just calmly replied "Yes, I know. I was in the gym."
Oh my god I was stunned at her reaction, she looked delighted and was practically drooling at the thought that I had been there and could give her first hand details. She composed herself and asked me what had happened (in a most put-on calm manner).
I did see what happened but I just said that the gym had been cleared and closed for a short time for the poor man's PRIVACY and that I hoped he was ok. She stared me out for a while but then gave up when I wasn't revealing any details.
I am horrified and sickened by her. She is usually like this with mundane gossip (ie she will drive past my mother's house and comment to me on her new hair cut - they have never met!!) but this was such an awful situation I can't believe she was so gossip-giddy about it!

Stupid horrid woman.
