Why did a girl once called Anne Frank ugly and even had the nerve to compare me to her?

Way back in middle school and at the time, I rarely had any comeback for insults. I was shocked to be honest. This was coming from a nearly 17 year-old girl stucked in 8th grade. At the time I was 12-13 years old.

She told me straight fowards that I looked exactly like Anne Frank (I said nothing) but then she had to add ''She was ugly''.

Honestly, now years later I think Anne Frank was actually a cute girl. Plus, she died a horrible death. It's so shocking how a 17 year-old had no compassion for what happened to her.

I'm referring to the girl in the book ''The Diary of Anne Frank''.
