['I had some girls in middle school that were very very mean to me - the epitome of mean girls.', "That isn't cool. Are you ok?", 'Yeah, but they really made an impression I guess.  They pretended to be a boy that liked me and sent me notes and even a stuffed animal on Valentines.  Then told me it was them - can you imagine!?']
That is mean. Girls can be mean sometimes.
Some so-called friends sent me anonymous love-notes in middle school.  When I found out it was them doing it and not an actual boy, I was very very upset.
