I was in Bangkok on wednesday for the first time in four years. having stayed away for a while a few things I'd forgotten about stood out.
Number one was the over powering smell of sewage. If your anywhere outside it reeks. Some places it's extremely nasty, such as near the canals.
The mixture of pollution and humidity makes walking around really unpleasant.
I was surprised by the amount of major building work going on. I found myself near a place in chinatown where I lived in the early eighties. The only thing I recognised were the road names.
Bangkok is like another country.
