Out in a fairly park in fairly urban part of London today with kids
After playing outside we went in to the cafe and sat down. I was hit by the most offensive smell ever - I thought first that someone near us had terrible halitosis or a strange body odour (it was a really bacteria-y stench, like something was dying - mixed with a weird sort of bleachy, burning rubber scent)
Turns out it was emanating from mud on toddler DDs boots 
.
Double bagged and took home, where I have spent half an hour scrubbing with bleach and everything else I could lay my hands on. The mud is gone but the fucking stink is still there.
It’s not dog poo I don’t think- the smell is a very odd, distinctive one. Did she step in decomposing squirrel entrails maybe? Anyone had this?? The boots have now been put outside in the bin.
