"My daughter goes to Eagles' games with her grandfather and my son and I go to Fremantle games," she said.
"We have only ever sat together at one Derby.

Her office is a shrine to Freo and she is often visited by other Freo diehards.
Donna has FFC plates on her car and says she breathes Freo from March to September.
"I keep my son in Freo guernseys through every growth spurt and he has kept his small ones that have been signed by all the players at Freo fun days," she said.
She is a big fan of being in the crowd at Freo's home games.
"I love the games, I never tire of them," she said.
"The supporters are awesome, so many different characters."
