Her reaction is expected but doesn't take away the fact she pretty much was very disrespectful to the person who raised her and loved her as her own.
Oh I don't know.. maybe it's because she has been lying to her for 12 ****ing years..? Ever thought about that? Pretty sure if someone has been lying to you or keeping a huge secret from you for 12 years that involves your
entire life and
where you came from then you would be acting the same way too, so don't sit here and tell me that you would be 'respectful' to someone who lies to you about your birth, gets mad at you and breaks your own house, and makes up BS about your own husband wearing glasses or not.
Maybe if Sakura actually told her the truth from the beginning instead of acting feeble and stupid then she wouldn't be acting like this, but no. She has to sneak outside of the damn village with questions just to get an answer, since she can't seem to get a solid answer from anyone in the village including her own damn "mother" and find answers from her father who doesn't even recognize her existence only until she says something.
Regardless if Sakura is taking care of her or not is not the problem and I don't know why people keep repeating it as if that matters. Salad didn't ask for that life nor did she ask to be born into a shitty world with foolish parents, so I don't see how
finding out about her real life and birth is being disrespectful when the same people she is trying to ask are being idiots about it. The only person who seems to be helping her is Suigetsu and he's not even from the their village.
Someone that I have been calling "mom" for 12 years only to find out that she is not my real mom, and you expect me to be calm about it?
My dads an a$$hole and never visits me and doesn't even remember what I look like and you expect me to be calm about it?
My home is destroyed because my so called "mom" has anger issues and you expect me to be calm about it?
No one in the village will tell me how I was born and you expect me to be calm about it?
I go and search for my father for the first time in my life and he tells me to mind my own business and you expect me to be calm?
Yeah my whole life is one giant lie, but I should be respectful to some woman who was part of the giant lie all because she took care of me for 12 years. Yeah, no, that's not how it works. In those 12 years that you have been taking care of me you have been lying to me for 12 years as well, so congrats.
EDIT: and for someone who supports Bolt and his stupid reasons for neglecting his father, I don't think you should be throwing around the word 'disrespect'. Bolt is the epitome of disrespect.
