True (T), False (F) or Not given (NG).
A new hobby
I saw some table tennis on TV and found it
quite interesting, so I thought I'd see if
there was a club or association in my area.
I looked everywhere, but unfortunately, the
nearest club was 100 kilometers away. So
without any knowledge, I decided to form
my own club. It was very hard in the
beginning - I didn't have any equipment
and I had to convince people that it was an
enjoyable way to keep fit. I organized a
small competition, which was a lot of fun,
and things started to grow from there.
Now we have full time training and our
opponents come from all over the country.
One of our members was even a bronze
medalist in the national championship.
Now we're also thinking of adding other
sports in our club, like tennis and
badminton,
The writer thought that table tennis was
boring.
