The dog-loving team of @Snazy, @Baileysmum, @RachaelDunlop and others have a successful thread on recognising them via their dogs; even organising doggy meet-ups.
For the non dog owners, or even those with pets less inclined to being led around the area on a lead, there are other ways to recognise your fellow SE23.LIFErs.
In my case it will probably be my hats. As a reluctant participant in the non-amicable split between my scalp and hair-growing follicles, wearing a hat when it is too cold / too hot / too sunny / too wet / too natural has become second-nature.
In which case you might see me drifting past wearing one of my collection - either my Stetson Fedora, or maybe the Panama, or possibly what my wife calls my 'Fidel' hat (for exercise and gardening mainly).
What makes you recognisable? I'd love to be able to bump into you in the street and say hello.
