Not sure where this came from

...but it was lying in a soggy mess on the path as I left for work. I pondered deeply as to whether I was going to add it to my recycling bin, but as my bin wasn't emptied last time, and we now have recycling collections suspended until this current bin people strike is resolved it went in the empty recycling bin shared by the six flats next to me. It's highly likely it's blown from that direction anyway.
