Many kids may be relieved to go back to school after a long and boring summer holiday. Holidays may be painful rather than enjoyable if the fear of traffic and strangers keeps them off the streets and up all day. Are the days of children roaming their neighbourhood till their parents call them in at dusk for dinner gone forever? I’d like to believe that with liveable cities, we can replace the aggressive noise of vehicle horns and engines with the sound of laughing, playing, distinctly not bored children.
