hey,I like smoking, said Tom. it is easy .
It's nothing , said Joe. I m going to smoke every day.
But after ten minutes Tom and Joe got quieter and quieter and their faces went an interesting colour.
London taxis are called 'black
cabs'. Most of them are black, but
some are not. You can stop one if it
has a 'For Hire' sign on it. The
drivers are usually friendly and
helpful.
