Recently my seven-year-old daughter asked me what “mellow” meant. I rather struggled to define it.
I could have just shown her an English autumn day. For me, it expresses exactly that “ pleasantly soft, sweet, ripe” sense given by my dictionary.
Rather than moving on to quote the much-abused line from Keats, I will simply post some photos of autumn in the Northeast of England last weekend, to make my point.
