When I was younger & the idea of personal transport was still a novelty, me & my friends would drive around town & shout 'nice things' out of car windows at strangers, ''you look lovely'' etc. In later years I walked around late at night, writing similar notes on scraps of paper & putting them in telephone boxes & on benches for people to find. Around the same time, my friend Charlie wrote, ''It's nice to be nice'' on a wall near the local college in permanent marker
