A girl sat in the waiting area of an internationally-recognized English language school, was wearing a T-shirt with a message that was, it has to be said, 'slightly out of the ordinary'.
The girl, aged about 13, was wearing the white T-shirt emblazoned in black letters with the words 'I love Bukkake'.
Actually, it didn't say 'love', but it had a red heart which is commonly used to signify the word 'love'.
Bukkake is something practised in Japan between one woman and as many as 100 men, and isn't really the sort of thing you'd expect to see promoted on a T-shirt worn by a young girl.
Still, this was Bangkok.
The scene was witnessed by Moys Kenwood, 48, another teacher from Canada called Jason, and several others, at inlingua's Rama 2 branch.
Jason looked carefully at the shirt, and then the girl's face, before saying:
"That's so wrong, man, on so many levels."
Several people chuckled.
