Thanks for the kind words all...
Now of course, we start asking ourselves, what, why, when...because short of a post mortem, we dont REALLY know what he's died from.
And as we talk about it...awful coincidences start to appear (although it's easy to put 2 and 2 together and come up with 5)
With hindsight, he's not been himself, (a little subdued maybe) for a couple of weeks.....and what happened a couple of weeks ago...the local council cleared the footpaths at the rear of the house, and it's just occured to us, they nearly always spray weedkiller.
It's no help in the end worrying about if, buts and maybe's...but it's a sobering thought...if the landscapers are out...beware. It hadnt even occured to me.
