Some cities you see once and you're done -- Rome was like that -- but others seem endlessly fascinating and you know you will be back -- Paris, Bangkok, St Petersburg, New York, Venice and now Florence.
"And who by fire, who by water,
who in the sunshine, who in the night time,
who by high ordeal, who by common trial,
who in your merry merry month of may,
who by very slow decay,
and who shall I say is calling?"
