Well, more like grin from ear to ear than smile, really:
- In the main shopping street in Liverpool: one of the local tramps dressed in an immaculate full evening suit, contentedly walking along, smoking a two-foot-long cigar.
- At the side of the road near my house: an elderly couple walking their elderly dog. Hanging delicately from the dog's mouth, a small, knotted plastic bag with some poo in it. I assume it was the dog's own poo, but it was hard to tell.
