<human>: Could you distill the essence of the text into 1-3 sentences?

When I was 12 years old and I first started middle school, I remember there was this girl in my class who was constantly being condescending to me. At the time, I thought she actually wanted to be my friend so I sat with her and her friends at lunch. She was constantly talking down to me and being patronizing and sarcastic, looking back at it it was so obvious she was being mean to me. Everything she told me, I believed it. She even said "God! You're so gullible!" Later on I found out she was always talking bad about me and she was saying I was annoying. As an adult, I don t understand it. What part of me thought that she actually wanted to be my friend? Why was I that gullible?

I'm a female btw
<bot>: I thought that this mean girl actually wanted to be my friend and I was stupid enough to go sit with her and I got burned. Why was I that foolish?
