I think this comes down to a quirk of personality.

I have always charmed parents even though I’m somewhat rough around the edges (probably partially because my mom died when I was young and older women still see me as a little lost lamb who needs mothering in my thirties), but my best friend near universally turns parents off, even though we’re pretty similar.

When we were younger, everyone thought she was a bad influence on me, though it was probably the other way around.
