Why do people think the writer is mad?

Aeroplanes are slowly driving me
mad
. I live near an airport and passing planes
can be heard night and day. The airport was built years ago, but for some
reason
it
could not be used then. Last year
, however
, it came into use. Over a hundred people
must have been driven away from their homes by the noise. I am one of the few
people left. Sometimes I think this house will be knocked down by a passing plane.
I have been offered a large
sum
of money to go away, but I am
determined
to stay
here. Everybody says I must be mad and they are probably right.
