Stepping off the plane

In 1974 I stepped off the plane into an oven. with waves of heat coming off the tarmac it was stifling, on leaving the UK we (my sisters and I) thought we would be living in mud huts but were surprised to find a very modern city, in not time at all we came across our first wild life in the guise of a cockroach measuring about two inches we were surprised to say the least.
On moving into the suburbs of Johannesburg it was disturbing to see metal bars on all the windows and a small house at the bottom of the garden apparently for the house cleaner and garden boy, servants? of cause my mother being a Brit, straight off the plane, wasn't having no strange woman in her house.
For me school was different too as apart from the fact it was all white the kids seemed to have a code, me being disabled and used to getting picked on by the British schooling system found that no one said a bad word to me, finding out later that if anyone was to pick on someone disabled then they would have been quietly taken aside and shown the error of they're ways, to say the least it was refreshing.
