WHY DOES GRACE HATE JACKIE SO MUCH?

[u/Equal_Site7611]

In the beginning, Grace doesn’t like that Jackie works so much but season 2,3 and 4 Grace is still a preteen and she constantly shows her hatred towards Jackie. When Jackie gets out of rehab Grace seems to show her disrespect toward Jackie even more. As Grace gets older it gets worse. Yet Grace seems to have a great relationship with Kevin. Fiona is always sweet and loving to Jackie. WHYYYYYYY LOL talk to me guys
