Questions: Flirting

An insecure hot girl told me this.
She said most hot girls have an ugly friend
She did not refer to herself as insecure in this discussion (But she once told me she was insecure when she was drunk)

Everyone is talking about girl friendzoning a guy. But girls, have you ever been friendzoned by guy?

So my sister in law came to visit with my aunt the last day and when we were sitting around the table, my sis in law pressed her toes against mine once. I thought it was a mistake. But then in a few seconds, she did it again. And again and again, until I acted innocently, looked under the table, and withdrew my leg, just so that it doesn't turn awkward because my mom and aunt were also there.
She is 27-30 years old while I'm just 20, her husband is my elder cousin brother and I think we both had an interesting conversation. Can it mean that she was flirting with me? Was I right to withdraw my leg? How should I deal with her the next time I meet her?

How would you react if someone called you goldilocks. Would you be angry or feel nice or will you show it dosen't matter a lot kind of attitude😂😂.
(Assuming he calls you goldilocks in a nice way not acting like a fuckboy).
I personally think it is not an offensive term.
