There were many visits to Iceland and he contacted us.”She said what was nice about Pistorius was that he usually asked about the wellbeing of her daughter‚ who was three years older than her son.This was because parents with a disabled child usually showered the disabled child with attention.“Oscar always asked about her‚ talked to her and made sure she was never left out.” – TMG Digital..
