Shouldn't they stop calling Donald 'Mr Davenport'?
He is their uncle and their surrogate father so why not call him "Dad" if not "Uncle Donald"?
shareI guess they've just been doing it for so long, its difficult to shake the habit. They still clearly think of him as there father.
I'm betting the reason why there so formal, is cause Donald never felt like there father, cause he always knew he didn't create them.
