They hold no grudges and want him to know they have "already forgiven him".
"We know he is very, very distraught himself.
"We really, really feel for the man."
Muir said Meddy was due to get hearing aids the day after the crash so probably didn't hear the motorbike travelling towards her. He also said it would have been difficult for the motorbike rider to see her as she feels the cold and was wearing a black puffer jacket.
"I don't think she heard the bike coming but she saw the kids across the road. She crossed the road to console the children."
He said being with children was Meddy's greatest joy.
She had three stepchildren and four grandchildren through them and her own son.
He said she was like a "pied piper" and her nieces and nephews call her a second mum.
He thinks the kids connected with her partly because she was just 144cm tall.
"She just about loved everybody's kids ... She just looked after them all."
