Aah, some people are so very sad aren't they, feeling the need to undermine other peoples achievements and happiness because their own lives are so pitifully empty.
Your achievement is fantastic, and I don't doubt with a supportive sister like you, your sis will be on the mend and on SW again asap.
What a sad little man he is.
Good luck and thanks for sharing... we all have someone like that in our lives who feels the need to make us feel inferior (mine is a "Great" Aunt whose favorite greeting is "Oh you really shouldnt wear skirts, you have huge legs, and footballers knees"... REALLY!)... it always, always says more about them than you xxxx
