I’m a puddle that peaked in medieval times, I go around houses like property lines. I don’t wave hello, I just sit and float What am I?

Exuberant prices A place filled with vices Traffic jams galore Makes you wish you could soar The constant smell of pis And that's not a diss Housing many, home to some Come downtown, let's have some fun

A silent cloak of gray descends, a city’s breath it deftly blends, sun’s golden gaze it often mends, a hazy veil where vision bends.

I am announced before I arrive, yet I still take many by surprise. I am given a human name, but no human can command me. I draw strength from warm oceans, and leave behind new shapes to familiar coasts. From far above, I look like a perfect spiral, but on the ground, I am anything but orderly. What am I?

A body of water that proves that isolation is safety.
