I know what’s an uncle and niece’s relationship

 I heard, you had a past with him. An uncle and a niece perfect family relationship with your mother and his wife and Weasley. Didn’t he just left Weasley and his mother to die in America, and my father lives at her place and Tina didn’t really like it? Because my father does not clean with lots of newspapers ? That’s a perfect family image ... ...so you had a past with him, you cannot or you are not allowed, or you gonna lose it all or you are not confident you charmed him enough with a working ethical like an adult ?
