It's not a glamorous picture but one I think is significant nevertheless.
So why did I snap a picture of the dirty pavement whilst cycling home?
For the word written on the ground. It reads ควย pronounced "kwai" (literally K-W-Y, pronouncing the first consonant in full) meaning buffalo in Thai.
Why on earth would someone write buffalo on the pavement? In the UK, it would be a little crazy but in Thailand there is an explanation.
Thailand hasn't developed anything like the range of swear words which the English-speaking West has. One of the rudest things you can call someone im Thai is buffalo...it really is an offensive term which will certainly not raise a smile.
So the graffiti, if we can call it so, is a rude word.
Funny to think that in writing buffalo someone out there did something rather naughty - hardly compares to what you find in London.
Now you can insult like a Thai though I don't condone doing so - you've been warned.
