I dont know any ESFPs but it looks like you have two options. Ignore her completely (cutting her out of your life or if you HAVE to see her, dont engage in any pleasantries and just keep to yourself) OR tell her directly what you dislike about her (i know this is probably not your strong suit, but if you dont tell her who will?) you can be polite about it as long as all the things you dislike are covered clearly.
Good luck!

 

I don't know why there are so many obnoxious ESFPs out there...I am an ESFP (possible ESTP) but I am reserved around virtual strangers, so I don't know what to tell you. I can tell you that I love ISFJs though!

If you say something to her she will either back off with her tail between her legs or she will simply try HARDER, I think. Sounds like she has some issues. I honestly hate people who always feel the need to talk and be disruptive during class. SAVE it, I say. I particularly hate when some suck up hand raiser who's not as smart as they think they are always wants to try and lead the class though. XD

It is quite possible your past experiences of ESFPs are coloring your feelings towards that bitch. Try and look at it objectively.

 

I know what you mean, though I mainly have more problems with ESFJs than I do with ESFP's.
Sometimes you just have to be blunt.
We were watching Chicago in Drama class once. We had all already seen it so we were just watching songs. A girl who claims to be an INFJ though I suspect is an ESFJ kept commenting on how creepy he looked, and kept talking about it through the song with little response. I eventually just said "Ok!" in a "We get it and be done with it" voice, and she stopped.
If you can figure out how to tell her to stop talking without being harsh, that should help.
