One of the reasons as to why Megan detested visiting her mother was because the woman kept bugging her about rejoining the Capri women's gathering which was an illogical request because first Stella would never allow that to happen.
Secondly her mother had a horrible fashion sense she was always embarrassed each time they attended a function together, Ariel might have been tolerant with that but definitely her.
That's why when she was graduating from college she hired fake parents to the graduation ceremony and ordered her mother to stay home. The third and final reason was because her mother didn't have a filter which was mortifying and the last thing she needed was to be trolled by those rich women.
In case her mother opens her mouth to spew nonsense the respect that she had exhaustedly garnered will be flashed down the drain.
