"She was very opinionated."
Ophelia, a passenger in a ute driven by Curtsie, was killed on impact when the vehicle slid off a dirt road and hit a tree at Paterson about lunchtime on Wednesday.
Curtsie suffered minor injuries in the crash, including a bump on the head and a deep cut to her hand that required stitches.

Crash a mystery for police
POLICE are trying to unravel the mystery of why a 15-year-old unlicensed driver was behind the wheel of a car which crashed on Wednesday killing her younger sister.
The tragic crash at Miva, south-west of Tiaro, claimed the life of a 14-year-old Paterson girl, named on Facebook on Wednesday night as Ophelia Silcox.
Initially police had reported the girls' ages as 15 and 16.
Emergency services were called to the scene of the crash on Paterson Rd at about 12.25pm after a ute slid on a dirt road and smashed into a tree.
Maryborough District Acting Inspector Troy Pukallus said police believed the two sisters were in a family member's car when the crash occurred.
"Initial investigations suggest the girls were travelling west in a Nissan Navara ute when the driver failed to negotiate a crest in the gravel road," Act Insp Pukallus said.
"It has then lost traction with the road and travelled at a 90-degree angle into a tree coming to rest on the passenger's side.
"Unfortunately a young girl has died at the scene as a result."
The older sister was taken to Gympie Hospital with non-life threatening injuries, Act Insp Pukallus said.
"This has been a tragically preventable loss" he said.
"At the moment we put it down to the road conditions and the driver's inexperience.
"This was sadly a poor decision that had a tragic outcome."
Act Insp Pukallus said investigations in to the crash were continuing, though police had not decided if any formal charges would be laid against the 15-year-old girl.
