I think the worst day of my life (so far) was when I was called from my class to the headmaster's office and was told 'It's nothing to worry about, but....... '.
As it turned out my daughter, then just a few months old had been rushed to hospital with breathing problems and what appeared to be collapsed lungs. Obviously not being there I had to be told the story. She had been staying with my mum as we were both at work when suddenly she went all limp and struggled to breath. Mum panicked, and not knowing what to do phoned for a taxi and took her to our GPs. Apparently when they went into the surgery alarm bells rang, they were took straight to a consulting room and the GPs who were on duty called from their patients. (I guess today they would have given her an appointment for a fortnight come Thursday).
The GPs immediately called for an ambulance and sent her to hospital. At some point on the journey the ambulance crew told my mum, 'don't worry but we are going to turn on the siren and put the blue lights on'. Goodness only knows how she felt, or how I would have felt if I were there. When I arrived my daughter was just lying there like a limp rag doll. I honestly feared the worst.
Anyway, after a few days in hospital, all was fine again and it was put down to just one of those things. She is now a healthy bouncing twenty eight year old who it was my great pleasure to see married earlier this year.
I'm sure, Jock, that in twenty or so years time you will be posting a similar story.
