oh dear- I did think most of you picked up that I fist came to London aged 19- not speaking much English (French MT) - but I did know the word 'puke' - and to my foreign eyes 'Pukka' seemed similar. Have you ever lived in a country where the language spoken (and written) is not your own? It does play all sorts of tricks on your brain, and gets you in all sorts of trouble.
Why the smile? Because a little indulgence for someone with another MT wouldn't go amiss. Some of you make horrendous spelling and grammatical mistakes in your own language- but I wouldn't dream of pointing it out, you see.
