Dear All
I am pleased to announce that I cleared out the shed and am still alive.
I didn't call the fire brigade for advice and thought, the next day, that the pile of chemicals / sweepings / rose clear didn't look too bad, so I piled it all into a few bags, safely knotted them and left them for my sturdy neighbour to take to the bins.
However, he has failed to do this, and bin day is tomorrow, so they could explode over the weekend. I'm in west London, if you see anything on newsroom southeast, its was me.
Thank you all.
