Seretse and Ruth's eldest son Ian,
who has been President of Botswana
describes leaving Croydon
and his parents' feelings
about their treatment.
"I think I was about three,
three and a half, years old
when I left the country.
The one thing that
always stands out clearly
is the party that was given
for my farewell party
by the nursery school
that I attended at the time,
and I think they made a cake
in the shape of an aeroplane
because I was going to be flying over.
They didn't want us to grow up
bearing any grudges against what
happened to them here.
They had decided to forgive and forget
the government of the day in the UK
which had treated them so badly.
I remember it wasn't really something
they really volunteered to come up with.
They just said well now is the present,
we live for the present and the future
and the past is behind us.
I never ever heard them
ever express any kind of bitterness."
