Conceited means full of yourself, I never said she was mean or said bad stuff about people. Also the first and second comments were jokes, as in, "I'm not adopted."
"Sounds like something an adopted person would say."
it's not flaunting extremely to say "I'm cool"
Flaunting extremely would be "I'm the coolest person I have ever met. I'm a great artist and dancer and singer and I'm rich and popular and be-a-u-ti-ful!!!!! 😄😊😃☺😉😍😘😌"
