Much excitement!

I am beside myself! #4 sister contacted me to have a little whisper in my ear. #2 sister is turning 50 in September and decided that she would like to celebrate by making the great trek from New Zealand to South Africa. #3 sister is also keen to come. The Matriarch of the family always visits every second year so she is also in on the act.
#1 sister (that's me!) is incredibly excited and has been given strict instructions by #4 sister to keep my mouth shut until they decide to let me know!
