Is it normal that my mom got angry at me for no reason for this situation?
Yesterday my mom and I were at a shop and this lady was insulting my mom and wanting to fight her and I was like "Mom, save your energy she isn't worth it" and then my mom goes around threatening to slap me in a public shop and the lady insulting my mom goes telling her to go back to her own country so then my other response to my mom was " Responding to her isn't going to do you any favors " but then she still got mad at me for it.
All I really wanted was for my mom to listen to me and to listen to her own advice.
[ FOR CONTEXT ABOUT THE ADVICE SHE ONCE TOLD ME: ARGUING BACK WON'T TO DO YOU ANY GOOD, IT'S BEST NOT TO RESPOND. ]
