My dad’s friend

So I don’t know if anyone has ever experienced issues like this with someone older but I was at an event with my dad and some people he knew and my best friend tonight playing trivia and this one woman was there and I swear to you I had no idea who she was. She was sitting next to my dad and kept saying she knew who I was (to her husband) and pointing at me which made me feel a bit awkward so anyways, my dad handed me a 20 to get something to eat and I didn’t want to get up to get it and I wasn’t even super hungry anyways and she kept making comments about me being spoiled and a millennial and ungrateful. Another lady there that I knew asked about what I was doing for work and I told her and then she asked my friend what she was up to and she said working and going to school and the other woman, looking at me, blurts out “YOU NEED TO GO BACK TO SCHOOL” and I told her “I am in school” and she was drinking wine and just kept making comments that I wasn’t sure if they were supposed to be funny but I was getting pissed. I was texting my friend next to me about it as well as my dad texted me and asked if she was aggravating me. Eventually her comments came to blows and she said I was being mean and that she could get mean and then she started acting I was getting mad and whatnot and I got so angry and tired of it that I stood up, fighting back tears, handed my dad back his money, grabbed my purse and stormed out. My friend followed me and as we got to my car the woman ran after me trying to apologize and I just lost my cool and told her I didn’t want to hear it and that I don’t even know her and she’s been making these rude comments all night and that I was leaving and she kept trying to convince me to stay and trying to apologize but I was so fed up I just got in my car. I understand that she may have thought she was joking and being funny at first but at some point she knew I was uncomfortable and aggravated and just kept going. It was my first time storming out of anywhere and my dad texted me to tell me she felt bad and I just said “good she should”
